The minuend is the number that is subtracted. The mathematical method of subtracting one number or quantity from another can be summarized as m-s=r, where m is the minuend, s is the subtraction and r is the difference.

For example, my mother only had three apples and gave them to my brother. My brother saw them and asked for my brother's apples. My brother gave me one. Then my brother's apple is subtractive, and so is my brother's apple. Three apples (minus)-1 apple (minus) =2 apples (minus).

The essence of subtraction:

Subtraction is the inverse operation of addition; Multiplication is a special form of addition; Division is the inverse operation of multiplication; Power is a simple form of multiplication; The root is the inverse operation of power.

Subtraction also follows predictable rules related to addition and multiplication, which can be proved, starting with integer subtraction and summarizing with real numbers and other things.
