subtrair 30 सेकंड में
- Subtrair means to subtract or take away.
- Primarily used in math to find differences.
- Can be used figuratively to reduce value or importance.
- Core Meaning
- The verb 'subtrair' in Portuguese primarily means 'to subtract' or 'to take away' from a larger quantity or total. It's the direct equivalent of the English word 'subtract' in mathematical contexts.
- Beyond Math
- Beyond arithmetic, 'subtrair' can also be used figuratively to mean 'to diminish,' 'to lessen,' or 'to deduct' from something abstract, like an effort, a quality, or even a person's importance. For example, one might say that a certain action 'subtracts' from someone's credibility. It implies a reduction or removal that makes the original entity smaller or less significant.
- Usage Examples
- In everyday life, you'll hear 'subtrair' most commonly when discussing calculations, shopping, or any situation involving numbers. If you are in a store and the cashier says 'Vamos subtrair o desconto' (Let's subtract the discount), they are explaining how the final price is calculated. In a more abstract sense, a teacher might explain that a student's lack of preparation 'subtrai' from their chances of success on an exam. It’s a versatile verb that moves from the concrete world of numbers to the more abstract realm of concepts and qualities.
- Figurative Use
- Think about situations where something is being removed or reduced. If you have 10 apples and you eat 3, you 'subtrai' 3 from 10. If a company's profits decrease, their profits have been 'subtraído' (subtracted from). Even in interpersonal dynamics, if someone's rude behavior 'subtracts' from their overall pleasantness, the verb is being used effectively. The core idea is always a removal or a decrease, making the original whole less than it was before.
Para calcular o lucro, é preciso subtrair os custos das receitas.
A falta de chuva pode subtrair valor à colheita.
O ladrão tentou subtrair o dinheiro da carteira.
- Mathematical Context
- In mathematics, 'subtrair' is fundamental. It's used in equations, calculations, and word problems. For instance, 'Doze subtraído de vinte é oito' translates to 'Twelve subtracted from twenty is eight.' This is the most direct and common usage.
- Financial Context
- In finance and business, 'subtrair' is used when discussing expenses, deductions, or losses. 'É preciso subtrair as despesas para saber o lucro líquido' means 'It is necessary to subtract the expenses to know the net profit.' This applies to personal budgets as well as corporate accounting.
- Figurative Language
- Figuratively, 'subtrair' can indicate a reduction in any kind of value or quantity. For example, 'A poluição subtrai qualidade de vida' means 'Pollution subtracts quality of life.' Here, it signifies a decrease or detriment rather than a numerical calculation. This usage is common in discussions about social issues, environmental concerns, or personal development.
- Everyday Scenarios
- Imagine you are planning a party and have a budget. You might say, 'We need to subtrair the cost of decorations from the total budget' ('Precisamos subtrair o custo das decorações do orçamento total'). Or, if you are discussing a recipe that requires removing certain ingredients, you might say, 'We must subtrair the seeds from the pepper' ('Devemos subtrair as sementes da pimenta'). The core concept of taking away remains consistent.
- Basic Structure
- The verb 'subtrair' typically follows the subject and is conjugated according to the tense and person. The object being subtracted is usually introduced by prepositions like 'de' (from) or 'a' (to/from), depending on the context. For example, 'Eu subtraio X de Y' (I subtract X from Y).
- Mathematical Usage
- In math, the structure is straightforward. 'Subtrair um número de outro' (to subtract one number from another) is the most common pattern. For instance, 'Cinco subtraído de dez resulta em cinco' (Five subtracted from ten results in five). The verb can also be used in imperative form, like 'Subtraia 5 de 15' (Subtract 5 from 15).
- Figurative Usage
- Figuratively, 'subtrair' often implies a negative impact. You might say, 'A falta de sono subtrai energia' (Lack of sleep subtracts energy). Here, 'energia' is the thing from which energy is being subtracted or diminished. The structure remains similar: Subject + subtrair + object (that is being diminished).
- Common Patterns
- * **Subtrair [algo] de [algo maior]:** To subtract [something] from [something larger]. Example: 'Subtrair os custos do orçamento.' (To subtract the costs from the budget.)
* **Subtrair-se a [algo]:** This is a reflexive usage meaning 'to abstain from,' 'to refrain from,' or 'to avoid.' Example: 'Ele se subtraiu à responsabilidade.' (He abstained from the responsibility.) This is a less common, more formal usage.
* **[Algo] subtrai [qualidade/quantidade] de [algo]:** [Something] subtracts [quality/quantity] from [something]. Example: 'A doença subtrai força do corpo.' (The illness subtracts strength from the body.)

- Verb Conjugation
- 'Subtrair' is a regular -ar verb in the present indicative, but it has an irregular past participle ('subtraído'). Here's a basic conjugation in the present indicative: eu subtraio, tu subtrais, ele/ela/você subtrai, nós subtraímos, vós subtraís, eles/elas/vocês subtraem. In the past participle, it's 'subtraído' (masculine singular), 'subtraída' (feminine singular), 'subtraídos' (masculine plural), 'subtraídas' (feminine plural).
- Examples with Different Tenses
- * **Present:** Eu subtraio 5 de 10. (I subtract 5 from 10.)
* **Past Perfect:** Ele subtraiu os custos da receita. (He subtracted the costs from the revenue.)
* **Future:** Nós subtrairemos os impostos do total. (We will subtract the taxes from the total.)
* **Imperative:** Subtraia a sua parte. (Subtract your share.) - Reflexive Use ('Subtrair-se')
- The reflexive form 'subtrair-se' means to withdraw oneself, to refrain, or to avoid. Example: 'O político se subtraiu às perguntas difíceis.' (The politician avoided the difficult questions.) This usage is more formal and less common than the direct meaning of subtraction.
- In the Classroom
- The most frequent place you'll encounter 'subtrair' is in a Portuguese language classroom, especially during math lessons. Teachers will use it extensively when explaining arithmetic operations. Phrases like 'Vamos subtrair 7 de 15' (Let's subtract 7 from 15) or 'Qual é o resultado de subtrair 3 de 8?' (What is the result of subtracting 3 from 8?) are standard. You'll also hear it in textbooks and on educational worksheets.
- Shopping and Commerce
- In stores, particularly when discounts or taxes are involved, 'subtrair' might be used. A salesperson might explain, 'Vamos subtrair o desconto do preço original' (Let's subtract the discount from the original price). While 'descontar' (to discount) is more common for the action of giving a discount, 'subtrair' can be used to explain the calculation process. You might also hear it in financial discussions about budgets or expenses.
- News and Formal Discussions
- In news reports, economic analyses, or formal debates, 'subtrair' is used to discuss reductions in figures, values, or benefits. For example, 'O governo anunciou que irá subtrair subsídios de alguns setores' (The government announced it will subtract subsidies from some sectors). This highlights the formal and often negative connotation of reduction in such contexts.
- Everyday Conversations (Figurative)
- In casual conversation, the figurative use of 'subtrair' is less common but still possible. Someone might say, 'Essa atitude subtrai valor à sua reputação' (That attitude subtracts value from your reputation). This implies that the action diminishes the person's standing. You're more likely to hear synonyms or other phrasing in informal chats, but it's good to recognize 'subtrair' in these contexts too.
- Online Content and Apps
- Educational apps for children learning math in Portuguese will frequently use 'subtrair'. You might also find it in online articles explaining financial concepts, budget planning, or even in recipe instructions that involve removing parts of ingredients.
Na aula de matemática, a professora explicou como subtrair números decimais.
O gerente informou que iriam subtrair os custos operacionais do faturamento.
- Formal Documents
- In legal documents, contracts, or official reports, 'subtrair' might appear when detailing financial calculations, deductions, or reductions in assets or liabilities. It lends a formal tone to the description of these financial adjustments.
- Scientific and Technical Texts
- In scientific papers or technical manuals, especially those involving calculations or quantitative analysis, 'subtrair' is used precisely. For example, 'Para obter a massa líquida, subtraia a massa do recipiente.' (To obtain the net mass, subtract the mass of the container.)
- Discussions about Resources
- When talking about the depletion of resources, be it natural resources or personal energy, 'subtrair' can be employed. 'A exploração excessiva pode subtrair a vitalidade da floresta.' (Excessive exploitation can subtract vitality from the forest.)
- Confusing 'Subtrair' with 'Adicionar' or 'Somar'
- The most fundamental mistake is using 'subtrair' when you mean to add. 'Subtrair' means to take away, while 'adicionar' or 'somar' means to add. For example, saying 'Eu subtraio 2 a 3' when you mean 'I add 2 to 3' is incorrect. Always remember 'subtrair' is about reduction.
- Incorrect Preposition Usage
- While 'subtrair X de Y' (subtract X from Y) is common, learners might misuse prepositions. For instance, saying 'subtrair X a Y' could be confusing or incorrect depending on the intended meaning. Stick to 'de' for the standard mathematical subtraction. The reflexive form 'subtrair-se a' has a different meaning (to abstain from), so be careful not to mix these.
- Overuse in Figurative Language
- While 'subtrair' can be used figuratively, it's not always the most natural choice in casual conversation. Native speakers might opt for simpler terms like 'diminuir' (to diminish), 'reduzir' (to reduce), or 'tirar' (to take away) depending on the nuance. Using 'subtrair' too frequently in non-mathematical contexts can sound a bit formal or stilted.
- Incorrect Verb Conjugation
- Like many verbs, 'subtrair' needs to be conjugated correctly. A common mistake is using the infinitive form when a conjugated form is needed, or using the wrong ending. For example, saying 'Eu subtrair 5' instead of 'Eu subtraio 5'. Pay close attention to verb endings for different tenses and persons.
- Confusing with 'Substituir'
- 'Subtrair' (to subtract) sounds somewhat similar to 'substituir' (to substitute or replace). These are entirely different verbs with different meanings. Ensure you are not mixing them up. 'Substituir' means to put something in place of another, not to take away.
Incorrecto: Eu subtraio 5 com 10. Correcto: Eu subtraio 5 de 10.
Incorrecto: A poluição subtrai para a qualidade de vida. Correcto: A poluição subtrai qualidade de vida.
- Misinterpreting the Reflexive Form
- The reflexive form 'subtrair-se' means to abstain or withdraw. Using it when you mean simple subtraction, or vice-versa, leads to misunderstanding. For example, saying 'Ele se subtraiu de suas obrigações' (He abstained from his obligations) is correct, but saying 'Ele subtraiu suas obrigações' would imply he somehow removed his obligations numerically, which doesn't make sense.
- Using 'Subtrair' for Physical Removal
- While 'subtrair' can imply taking away, it's not typically used for physically removing an object unless it's in a very specific, often mathematical or conceptual, context. For simple physical removal, verbs like 'tirar' (to take out), 'remover' (to remove), or 'levar' (to take) are more appropriate. For example, you wouldn't say 'Subtraia o prato da mesa'; you'd say 'Tire o prato da mesa'.
- Diminuir (to diminish, to decrease)
- 'Diminuir' is a very common alternative, especially in figurative contexts. While 'subtrair' implies a specific act of taking away, 'diminuir' refers more to the general process of becoming smaller or less.
Example: 'O preço diminuiu.' (The price decreased.) vs. 'O preço foi subtraído de X.' (The price was subtracted from X.) 'Diminuir' is often used for quantities, intensity, or size. - Reduzir (to reduce)
- 'Reduzir' is another strong synonym, particularly when talking about lowering something in quantity, scope, or intensity. It's often used in contexts of cost reduction, effort reduction, or lowering standards.
Example: 'Precisamos reduzir os gastos.' (We need to reduce expenses.) This is very similar to 'subtrair os gastos', but 'reduzir' emphasizes the outcome of making them smaller. - Tirar (to take, to remove)
- 'Tirar' is a more general verb for 'to take' or 'to remove'. It can be used in many contexts where 'subtrair' might apply, especially in everyday language.
Example: 'Tire o excesso de sal.' (Take away the excess salt.) vs. 'Subtraia o excesso de sal.' (Subtract the excess salt.) 'Tirar' is less formal and more versatile for physical removal. - Deduzir (to deduct)
- 'Deduzir' is very close to 'subtrair' in financial and accounting contexts. It specifically means to deduct an amount, often from a total, like taxes or expenses.
Example: 'Deduzir os impostos do salário.' (To deduct the taxes from the salary.) This is almost interchangeable with 'subtrair os impostos' in this specific context. - Omitir (to omit, to leave out)
- While not a direct synonym, 'omitir' can sometimes convey a similar idea of removing something, but it focuses on the act of leaving something out rather than reducing a total.
Example: 'Omitir a informação.' (To omit the information.) This is different from subtracting a numerical value. - Excluir (to exclude)
- Similar to 'omitir', 'excluir' means to leave out or prevent from being included. It's about setting something aside rather than reducing a quantity.
Example: 'Excluir certas opções.' (To exclude certain options.)
Em vez de subtrair, ele decidiu diminuir o preço.
O contador irá deduzir os impostos, que é similar a subtrair do total.
- Consider the Context
- The best alternative depends heavily on the context. For numerical operations, 'subtrair' and 'deduzir' are very specific. For general decreases in size, amount, or intensity, 'diminuir' and 'reduzir' are excellent choices. For simple physical removal, 'tirar' is usually the most common and natural verb.
- Formal vs. Informal
- 'Subtrair' and 'deduzir' tend to be more formal, especially in written or technical language. 'Diminuir', 'reduzir', and 'tirar' can be used in both formal and informal settings, with 'tirar' being the most informal of this group.

रोचक तथ्य
The Latin root 'trahere' (to draw, pull) is also the origin of many other English words related to pulling or drawing, such as 'attract', 'contract', 'distract', 'extract', 'protract', and 'tractor'. So, when you subtract, you are metaphorically 'drawing away'.

Both verbs refer to a reduction in quantity or value.
'Subtrair' implies a specific action of taking away a defined amount, often in a calculation. 'Diminuir' refers to the general process or state of becoming less or smaller, without necessarily specifying the exact amount removed or the action of removal itself.
Subtrai 5 da sua pontuação (Subtract 5 from your score - specific action) vs. Sua pontuação diminuiu (Your score decreased - general outcome).
Both are used in financial contexts for taking away amounts.
'Subtrair' is a broader term for subtraction. 'Deduzir' is more specific to financial or logical deductions, like deducting taxes from income or deducing a conclusion from evidence. In financial contexts, they are often interchangeable.
Subtrair os impostos do salário (Subtract taxes from salary) vs. Deduzir os impostos do salário (Deduct taxes from salary) - both are fine. However, 'deduzir uma conclusão' (deduce a conclusion) cannot be replaced by 'subtrair uma conclusão'.
Both mean to take away.
'Tirar' is a very general verb for removal, often physical. 'Subtrair' is more specific to numerical or abstract reduction, especially in formal or mathematical contexts. You 'tirar' a hat, but you 'subtrair' a number.
Tire o chapéu (Take off the hat) vs. Subtraia o número 3 (Subtract the number 3).
Both imply making something smaller.
'Subtrair' implies an active process of taking away a specific quantity. 'Reduzir' often refers to the outcome or the general act of making something smaller in size, scope, or intensity, and can be achieved through various means, not just direct subtraction.
Subtrair 10kg do peso total (Subtract 10kg from the total weight - specific action) vs. Reduzir o peso em 10kg (Reduce the weight by 10kg - outcome or general action).
They are opposites in arithmetic.
'Subtrair' means to take away, to find the difference. 'Somar' means to add, to combine quantities to find a total. They are antonyms.
Subtrair 5 de 10 = 5 (Subtract 5 from 10 = 5) vs. Somar 5 a 10 = 15 (Add 5 to 10 = 15).

शब्द की उत्पत्ति
The Portuguese verb 'subtrair' comes directly from the Latin verb 'subtrahere'. This Latin verb is a combination of 'sub-' (meaning 'under' or 'beneath') and 'trahere' (meaning 'to draw' or 'to pull').
मूल अर्थ: In Latin, 'subtrahere' meant 'to draw from beneath', 'to pull away', or 'to withdraw'. This literal meaning of pulling something away from underneath or from a larger whole directly informs its modern meaning of subtraction.
