What are the rules in subtraction?
Subtraction means to find the difference between two numbers. In a basic subtraction problem, the minuend is the larger number, and the subtrahend is the smaller number. The answer or solution to a subtraction problem is called the difference. Subtraction is the inverse or opposite operation from addition, but unlike addition, subtraction does not have a commutative property meaning that the order of the numbers will make a difference in the answer. 10 – 4 will not have the same answer at 4 – 10.
