تفریق کردن 30秒了解
- To subtract or take away a number from another.
- Primarily used in mathematical contexts.
- Can be used metaphorically to mean reduce or diminish.
- Formed from the noun 'تفریق' (subtraction) and 'کردن' (to do).
- Core Meaning
- The verb 'تفریق کردن' (tafriq kardan) fundamentally means to subtract or to take away one quantity from another. It is most commonly encountered in mathematical contexts but can also be used metaphorically to describe the reduction or lessening of something.
- Mathematical Usage
- In arithmetic and algebra, 'تفریق کردن' is the direct Persian equivalent of 'to subtract'. When you perform a subtraction problem, you are 'تفریق کردن' the smaller number from the larger one. For example, 'پنج منهای سه را تفریق کن' translates to 'Subtract three from five'. This is the most frequent and literal usage of the word.
- Metaphorical and Figurative Usage
- Beyond mathematics, 'تفریق کردن' can imply a process of diminishing, reducing, or separating. For instance, one might speak of 'تفریق کردن' differences between two groups, meaning to reduce or eliminate those differences. It can also refer to the act of making something less significant or removing parts of it. This figurative use is less common than the mathematical one but is still understood.
- Everyday Scenarios
- You will hear 'تفریق کردن' most often in educational settings, such as classrooms where math is being taught. It's also used in everyday conversations when discussing finances, quantities, or any situation where a reduction or subtraction is involved. For example, a shopkeeper might explain a discount by saying they 'تفریق کردن' a certain amount from the original price.
در ریاضیات، ما اعداد را تفریق میکنیم تا حاصل را به دست آوریم.
لطفاً این مبلغ را از کل حساب تفریق کنید.
- Nuances
- While 'تفریق کردن' is the most direct translation for 'to subtract', in some casual contexts, simpler verbs might be used, or the concept might be implied. However, for clarity, especially in formal or educational settings, 'تفریق کردن' is the preferred term.
- Basic Structure
- The verb 'تفریق کردن' is typically used with the object of subtraction following it, often preceded by a preposition like 'از' (az - from). The structure is generally: [Subject] + [Number/Quantity to be subtracted] + 'را' (ra - object marker) + [Number/Quantity from which to subtract] + 'تفریق کردن'.
- Mathematical Examples
- In math class, you'll see this frequently. For instance, to say '10 minus 4 equals 6', you might hear: 'ده را از چهار تفریق کنید' (dah ra az chahar tafriq konid - subtract four from ten) or more commonly in a problem setup: 'ده منهای چهار مساوی شش است' (dah menhay-e chahar mosavi-ye shesh ast - ten minus four equals six). The verb form 'تفریق کردن' is used when describing the action itself.
- Financial Contexts
- When discussing money or bills, 'تفریق کردن' is common. If a discount is applied, a sentence might be: 'آنها 10 درصد از قیمت اصلی را تفریق کردند.' (anha 10 dar sad az gheymat-e asli ra tafriq kardand - They subtracted 10 percent from the original price.)
- Everyday Reductions
- Even in non-mathematical scenarios, the concept of taking away can be expressed. If a group of people is reduced, one might say: 'تعداد افراد حاضر را تفریق کردیم تا بفهمیم چند نفر غایب هستند.' (tedad-e afrad-e hazir ra tafriq kardim ta befahmim chand nafar ghayeb hastand - We subtracted the number of present people to understand how many were absent.) This is a more figurative use.
پنج را از ده تفریق کنید، نتیجه پنج میشود.
ما باید هزینه اضافی را از کل صورتحساب تفریق کنیم.
- Verb Conjugation
- Like other Persian verbs, 'تفریق کردن' conjugates based on tense, person, and number. For example, 'تفریق میکنم' (tafriq mikonam - I subtract), 'تفریق کردی' (tafriq kardi - you subtracted), 'تفریق خواهد کرد' (tafriq khahad kard - he/she will subtract).
- Educational Institutions
- The most common place to hear 'تفریق کردن' is in a classroom setting, particularly during mathematics lessons. Teachers use it to instruct students on how to perform subtraction. You'll hear phrases like 'عدد کوچکتر را از عدد بزرگتر تفریق کنید' (subtract the smaller number from the larger number) or 'آیا میتوانید این مسئله را تفریق کنید؟' (Can you subtract this problem?). Textbooks and educational materials will also feature this verb extensively.
- Financial and Business Discussions
- In contexts involving money, budgets, or transactions, 'تفریق کردن' is frequently used. For example, when discussing discounts, a salesperson might say: 'ما 20 درصد از قیمت کل را تفریق کردهایم' (We have subtracted 20 percent from the total price). Accountants and financial advisors might use it when explaining deductions or expenses. Even in casual conversations about personal finances, like calculating change, the concept of subtraction is present and might be voiced using this verb.
- Scientific and Technical Fields
- Beyond basic arithmetic, in more complex scientific and engineering calculations, subtraction is a fundamental operation. 'تفریق کردن' would be used in discussions about data analysis, experimental results, or any process that involves calculating differences or removing components. For instance, in physics, one might describe 'تفریق کردن' a background reading from a measured value.
- Everyday Problem Solving
- While less common than in formal settings, 'تفریق کردن' can appear in everyday speech when describing a process of reduction or removal. If you're trying to figure out how many items are left after some have been used or given away, you might conceptually 'تفریق کردن' the used items from the total. However, in casual conversation, simpler phrasing might be preferred unless precision is required.
معلم از دانشآموزان خواست تا اعداد را در دفترشان تفریق کنند.
در گزارش مالی، هزینهها از درآمد کل تفریق میشود.
- Formal vs. Informal
- While 'تفریق کردن' is precise, in very informal spoken Persian, people might use simpler verbs or circumlocutions for subtraction if the context is clear. However, for any situation requiring mathematical accuracy or formal communication, 'تفریق کردن' is the standard and expected term.
- Confusing with Addition
- The most fundamental mistake for learners is to confuse 'تفریق کردن' (subtract) with its opposite, 'جمع کردن' (jam' kardan - to add). While both are mathematical operations, their meanings are diametrically opposed. Learners might mistakenly use 'تفریق کردن' when they intend to say 'add', leading to complete reversal of the intended meaning.
- Incorrect Object/Subject Placement
- Persian sentence structure, especially with compound verbs and object markers like 'را' (ra), can be tricky. A common error is misplacing the numbers or quantities involved in the subtraction. For example, saying 'پنج را از ده تفریق کن' (subtract five from ten) is correct, but saying 'ده را از پنج تفریق کن' (subtract ten from five) is mathematically incorrect and confusing, even if the grammar is superficially sound. The number being taken away should typically be marked with 'را' and come before the number from which it is taken.
- Ignoring the 'از' (from)
- The preposition 'از' (az - from) is crucial when specifying the number or quantity from which another is being subtracted. Forgetting to include 'از' can lead to ambiguous or grammatically awkward sentences. For instance, 'ده تفریق پنج' (ten subtract five) is not a proper sentence. It should be 'ده از پنج تفریق کن' (subtract five from ten) or 'پنج را از ده تفریق کن'.
- Using the Noun Instead of the Verb
- While 'تفریق' (tafriq) is the noun for subtraction, learners might mistakenly try to use it as a verb or in place of the verb phrase 'تفریق کردن'. For example, saying 'من تفریق کردم' (I subtractioned) is incorrect. It should be 'من تفریق کردم' (I subtracted).
- Verb Conjugation Errors
- As with any verb, incorrect conjugation is a common mistake. This includes using the wrong tense, person, or number. For example, using the past tense when the present is needed, or using the singular form when the plural is required.
اشتباه: پنج را ده تفریق کن. صحیح: ده را از پنج تفریق کن.
اشتباه: من جمع کردم 5 از 10. صحیح: من 5 را از 10 تفریق کردم.
- Over-reliance on Literal Translation
- Sometimes, learners might try to directly translate English sentence structures, which can lead to errors in Persian. For instance, trying to force the English phrasing 'subtract X from Y' directly might result in an unnatural Persian sentence. It's important to learn the idiomatic Persian way of expressing subtraction.
- کم کردن (kam kardan)
- 'کم کردن' literally means 'to make less' or 'to decrease'. It is a very common synonym for 'تفریق کردن', especially in less formal or more general contexts. While 'تفریق کردن' is precise for mathematical subtraction, 'کم کردن' can be used for reducing quantities, prices, or even effort. For example, 'قیمت را کم کنید' (kam konid - reduce the price) is often used interchangeably with 'قیمت را تفریق کنید' in a shopping context, though 'تفریق کردن' might sound slightly more formal or specific to a calculation.
- کسر کردن (kasr kardan)
- 'کسر کردن' is another verb that relates to subtraction, particularly in the context of fractions or division where a part is taken away. It can also mean 'to deduct'. While it shares similarity with 'تفریق کردن', 'کسر کردن' often implies taking a portion or a fraction. In advanced mathematics, it might be used more specifically. In general usage, 'تفریق کردن' is more universally understood for simple subtraction.
- حذف کردن (hazf kardan)
- 'حذف کردن' means 'to remove' or 'to delete'. While not a direct synonym for subtraction in a mathematical sense, it can be used in contexts where elements are taken away from a set or list. For example, 'نام او را از لیست حذف کنید' (hazf konid - remove his name from the list). This is about removal, not necessarily numerical subtraction.
- از بین بردن (az beyn bordan)
- This phrase means 'to destroy', 'to eliminate', or 'to get rid of'. It's a much stronger term than subtraction and implies complete eradication rather than a numerical reduction. It's not a substitute for 'تفریق کردن' in mathematical contexts.
- کاستن (kastan)
- 'کاستن' is a more literary or formal verb meaning 'to lessen', 'to diminish', or 'to subtract'. It is less common in everyday speech than 'کم کردن' or 'تفریق کردن' but can be found in more formal writing or older texts. It carries a sense of gradual reduction.
تفریق کردن (Tafriq kardan) vs. کم کردن (Kam kardan)
مقایسه:
1. ده را از پنج تفریق کنید. (Mathematical subtraction)
2. قیمت را کم کنید. (Reduce the price)
- Context is Key
- The choice of verb often depends on the specific nuance you want to convey. 'تفریق کردن' is the most direct and unambiguous term for subtraction in arithmetic. Other verbs like 'کم کردن' offer more flexibility in meaning, covering reduction and decrease more broadly.
How Formal Is It?

如何使用
High (in mathematical and financial contexts); Medium (in general reduction contexts)
-
Confusing 'تفریق کردن' with 'جمع کردن'.
→
Use 'تفریق کردن' for subtraction and 'جمع کردن' for addition.
These are opposite operations. 'تفریق کردن' means to take away, while 'جمع کردن' means to bring together. For example, 5 - 3 = 2 ('پنج را از هشت تفریق کن') but 5 + 3 = 8 ('پنج را با سه جمع کن').
-
Incorrect order of numbers in subtraction.
→
The number being subtracted is typically marked with 'را' and comes before the number from which it is subtracted.
Saying 'پنج را از ده تفریق کن' (Subtract five from ten) is correct. Saying 'ده را از پنج تفریق کن' implies subtracting ten from five, which is mathematically different and usually leads to a negative number or is simply stated incorrectly.
-
Forgetting the preposition 'از' (from).
→
Always use 'از' to indicate the number from which another is being subtracted.
It should be 'ده را از پنج تفریق کن' (Subtract five from ten), not 'ده پنج تفریق کن'. The 'از' is essential for clarity.
-
Using the noun 'تفریق' as a verb.
→
Use the compound verb 'تفریق کردن'.
You cannot say 'من تفریق کردم' meaning 'I subtracted'. It must be 'من تفریق کردم' (I subtracted). The noun 'تفریق' means 'subtraction'.
-
Incorrect verb conjugation.
→
Conjugate 'تفریق کردن' according to tense, person, and number.
Forgetting to conjugate correctly, e.g., using the infinitive form in a sentence, or using the wrong ending. For instance, 'او تفریق کردن' is incorrect; it should be 'او تفریق میکند' (he/she subtracts) or 'او تفریق کرد' (he/she subtracted).
小贴士
Mastering 'را' and 'از'
The correct use of the object marker 'را' and the preposition 'از' is crucial for forming accurate subtraction sentences. Remember that the number being subtracted is typically marked with 'را' and comes before the number from which it is subtracted, with 'از' connecting the two. For example: 'پنج را از ده تفریق کن' (Subtract five from ten).
Synonym Awareness
While 'تفریق کردن' is precise, be aware of synonyms like 'کم کردن' and 'کسر کردن'. 'کم کردن' is more general (to reduce), while 'کسر کردن' often implies deduction or dealing with fractions. Using the right synonym adds nuance to your Persian.
Rolling Your 'R's
The Persian 'ر' (r) is often rolled or trilled, similar to Spanish or Italian. Practicing this sound, especially in words like 'تفریق' and 'کردن', will significantly improve your pronunciation and make you more understandable.
Mathematical vs. Metaphorical Use
Understand when 'تفریق کردن' is used literally for calculations and when it's used metaphorically for reduction or diminution. Context is key to interpreting its meaning correctly.
Construct Your Own Problems
Create simple subtraction problems in Persian and write them out or say them aloud. This active practice solidifies the sentence structures and vocabulary.
Visual Association
Create a visual image for 'تفریق کردن'. Imagine a magician performing a 'trick' (sounds like tafriq) to make numbers disappear from a group. This mental image can help you recall the word and its meaning.
Opposites Matter
Always learn antonyms together. Knowing that 'جمع کردن' (to add) is the opposite of 'تفریق کردن' (to subtract) helps reinforce the meaning of both words.
Real-World Scenarios
Think about how subtraction is used in your daily life (e.g., managing a budget, calculating change) and try to express those scenarios in Persian using 'تفریق کردن' or related terms.
Root Meaning
Understanding that 'تفریق' comes from an Arabic root meaning 'separation' or 'distinction' can provide a deeper grasp of why it signifies subtraction.
Listen and Repeat
Listen to native Persian speakers using 'تفریق کردن' in videos, podcasts, or conversations. Try to repeat the sentences, paying attention to pronunciation and intonation.
记住它
记忆技巧
Imagine a 'trick' (sounds like tafriq) where you're trying to trick someone by taking away their money. Or, think of a 'far-off' (sounds like fariq) place where you send things away to subtract them.
视觉联想
Picture a large pile of apples. Then, a hand comes and 'takes away' (subtracts) some of them. The apples being taken away are 'تفریق' (tafriq). The action of taking them away is 'تفریق کردن'.

词源
The word 'تفریق' (tafriq) comes from the Arabic root ف-ر-ق (f-r-q), which means 'to divide', 'to separate', or 'to distinguish'. In Persian, it evolved to specifically mean 'subtraction' in a mathematical context, often combined with the verb 'کردن' (kardan - to do/make) to form the compound verb 'تفریق کردن'.
原始含义： Separation, division, distinction.
Semitic (Arabic origin, adopted into Persian)文化背景
The term 'تفریق کردن' itself is neutral and purely mathematical. However, its application in contexts like financial disparities or resource allocation could indirectly touch upon sensitive social or economic issues if not handled carefully in broader discussions.
In English-speaking cultures, the term 'subtract' is similarly core to mathematics and everyday calculations. The structure and usage patterns of 'تفریق کردن' in Persian mirror those of 'subtract' in English, reinforcing its role as a foundational mathematical verb.

常见问题
10 个问题While both relate to reducing a quantity, 'تفریق کردن' is specifically the mathematical operation of subtraction, meaning to take one number away from another. 'کم کردن' is a more general term meaning 'to reduce' or 'to decrease' and can be used in broader contexts, such as reducing prices or quantities without necessarily performing a precise mathematical calculation. In mathematical contexts, 'تفریق کردن' is preferred for accuracy.
You can say 'ده منهای سه' (dah menhay-e se). If you want to use the verb 'تفریق کردن', you would say 'ده را از سه تفریق کنید' (subtract three from ten) or more commonly, 'ده منهای سه میشود هفت' (ten minus three equals seven).
Primarily, yes. Its core meaning is mathematical subtraction. However, it can be used metaphorically to mean 'to reduce', 'to diminish', or 'to take away' in a non-numerical sense, for example, 'تفریق کردن تعصبات' (subtracting biases). But its literal and most common usage is in mathematics and finance.
The noun form is 'تفریق' (tafriq), which means 'subtraction'.
Yes, especially when discussing finances, bills, or simple calculations. For example, 'لطفاً این مبلغ را از کل صورتحساب تفریق کنید' (Please subtract this amount from the total bill). In very casual contexts, 'کم کردن' might be used more frequently for general reductions.
Common mistakes include confusing it with 'جمع کردن' (to add), using the wrong order of numbers (e.g., subtracting the larger from the smaller incorrectly), forgetting the preposition 'از' (from), or misconjugating the verb.
You would say 'پنج را از ده تفریق کنید' (panj ra az dah tafriq konid) for a formal command or 'پنج را از ده تفریق کن' (panj ra az dah tafriq kon) for an informal command.
The direct opposite verb is 'جمع کردن' (jam' kardan), which means 'to add'.
Yes, the passive form is 'تفریق شدن' (tafriq shodan), meaning 'to be subtracted'. For example, 'این مبلغ از حساب شما تفریق خواهد شد' (This amount will be subtracted from your account).
'کسر کردن' is often used when deducting specific amounts like taxes, fees, or interest, or when dealing with fractions. 'تفریق کردن' is the more general term for subtraction. For instance, 'مالیات را کسر کردند' (they deducted the tax) is common, whereas 'مالیات را تفریق کردند' might sound slightly less idiomatic in that specific context.

Summary
The verb 'تفریق کردن' (tafriq kardan) is the direct Persian term for 'to subtract'. It is most commonly used in mathematical and financial contexts to denote the operation of taking one quantity away from another. While it can also be used metaphorically to mean 'to reduce' or 'to diminish', its core meaning remains rooted in calculation and numerical reduction. Understanding its structure as a compound verb ('تفریق' + 'کردن') is key to mastering its usage.
- To subtract or take away a number from another.
- Primarily used in mathematical contexts.
- Can be used metaphorically to mean reduce or diminish.
- Formed from the noun 'تفریق' (subtraction) and 'کردن' (to do).
Mastering 'را' and 'از'
The correct use of the object marker 'را' and the preposition 'از' is crucial for forming accurate subtraction sentences. Remember that the number being subtracted is typically marked with 'را' and comes before the number from which it is subtracted, with 'از' connecting the two. For example: 'پنج را از ده تفریق کن' (Subtract five from ten).
Synonym Awareness
While 'تفریق کردن' is precise, be aware of synonyms like 'کم کردن' and 'کسر کردن'. 'کم کردن' is more general (to reduce), while 'کسر کردن' often implies deduction or dealing with fractions. Using the right synonym adds nuance to your Persian.
Rolling Your 'R's
The Persian 'ر' (r) is often rolled or trilled, similar to Spanish or Italian. Practicing this sound, especially in words like 'تفریق' and 'کردن', will significantly improve your pronunciation and make you more understandable.
Mathematical vs. Metaphorical Use
Understand when 'تفریق کردن' is used literally for calculations and when it's used metaphorically for reduction or diminution. Context is key to interpreting its meaning correctly.
