Subtraction is the inverse of addition and involves taking away or comparing sets. It is represented by the minus sign and involves a minuend, subtrahend, and difference. The minuend is the number being subtracted from, the subtrahend is the number being subtracted, and the difference is the result. Subtraction can be used to find missing addends as the inverse of addition.
