Explanation at your level:
To subtract is to take numbers away. If you have 10 and you take 2, you have 8. You use this word in math class to find the answer. It is very useful for shopping or counting your toys.
When you subtract one number from another, you find the difference. We use it when we want to know how much is left after we remove something. For example, 'Subtract 5 from 20 to get 15.'
The verb subtract is commonly used in academic and financial contexts. It implies a systematic removal of a quantity. You might subtract taxes from your salary or subtract the weight of a container to find the net weight of the contents.
Beyond mathematics, subtract is used metaphorically. You might say that a specific error subtracts from the credibility of an argument. It is a precise way to describe how one element reduces the value or impact of the whole.
In advanced contexts, subtract denotes the process of isolating a variable by removing extraneous factors. It is frequently used in scientific research, logic, and formal analysis to describe the removal of specific components to observe the remaining core.
Historically and linguistically, subtract carries the weight of its Latin roots, implying a 'drawing away' of parts. In literary or philosophical discourse, it can signify the stripping away of superficial layers to reveal an underlying truth, often used in complex analytical writing.

In a more general sense, you can subtract from someone's reputation or from the overall enjoyment of an event. For example, a rainy day might subtract from the fun of a picnic. It is all about reduction and taking things away from a whole.
The word subtract comes from the Latin word subtrahere, which is a combination of sub (meaning 'from under') and trahere (meaning 'to draw' or 'to pull'). Literally, it means to pull something out from underneath a pile.
It entered the English language in the 15th century through Middle French. It is fascinating to see how a word that started as a physical action of pulling something out became a core term for abstract mathematical operations.
