Which operation should be used to check if the difference of two values is greater than 1?

The question asks to check for the "difference of two values." The mathematical operation used to find the difference between two numbers is subtraction. After performing the subtraction, the result can then be compared to see if it is greater than 1. For example, to check if the difference between x and y is greater than 1, you would compute x - y and then evaluate if the result is > 1.

A. Multiplication is used to find the product of two values, not their difference.

C. Addition is used to find the sum of two values, not their difference.

D. Division is used to find the quotient of two values, not their difference.
