Here's why:
* Subtraction is an operation, not a noun: "Subtract" is the verb, and "subtraction" is the noun describing the process. Prefixes and suffixes typically modify nouns or verbs.
* Mathematical operations are often represented by symbols: The "-" symbol is the standard way to indicate subtraction.
However, you might find some words related to subtraction that use prefixes or suffixes:
* "Minus" is a synonym for "subtract," but it's not a prefix or suffix itself.
* "Subtrahend" is the number being subtracted, but it's a specific mathematical term.
* "Difference" is the result of subtraction, but it's not directly related to the subtraction process itself.
So, while there's no single prefix or suffix that explicitly indicates subtraction, the operation is clearly defined by the "-" symbol and the words used to describe the process.
