# What is the rule for subtracting?

Subtraction is the way to find the difference between two numbers. In basic subtraction, your student will begin by subtracting a smaller number from a larger number. Once they have mastered basic subtraction, they will advance to multi-digit problems and learn long subtraction using regrouping or borrowing to solve a subtraction problem. The order of the numbers in a subtraction equation will impact the answer as subtraction does not have a commutative property.
