What is the input called that represents the number being subtracted in a subtraction operation?

In a subtraction operation, the input that represents the number being subtracted is referred to as the subtrahend. This term specifically designates the quantity that is taken away from another quantity, known as the minuend.

To understand this better, consider an example where you subtract 5 from 10. In this case, 10 is the minuend because it is the original number from which something is being removed, and 5 is the subtrahend since that is the number that is being subtracted. The result of this operation, known as the difference, is what you obtain after performing the subtraction.

Recognizing the roles of these different components in subtraction is crucial for mathematical comprehension, as it helps clarify the relationships between the numbers involved.
