Question: 1 / 400

Which mathematical operation is used to find the difference between two numbers?

Addition

Multiplication

Division

Subtraction

To determine the difference between two numbers, the operation used is subtraction. Subtraction involves taking one number away from another and is typically represented by the minus sign (−). For example, if you have two numbers, say 8 and 3, and you want to find the difference, you would calculate 8 - 3, which equals 5. This operation is essential in various mathematical contexts, from basic arithmetic to more complex problem-solving scenarios, where understanding how to manipulate quantities is crucial.

In contrast, addition combines two numbers to form a larger quantity, multiplication increases a number by a factor of another number, and division splits a number into smaller parts or groups. These operations serve different purposes and do not yield the difference between two numbers as subtraction does.
