Difference is a fundamental concept in subtraction, representing the result of subtracting one number from another. For example, in the subtraction problem

the difference is 4. This concept is crucial for understanding arithmetic operations and solving mathematical problems.

In mathematics, difference is symbolized by the minus sign (-). It is used to determine how much one number is greater or smaller than another. Understanding difference helps students develop problem-solving skills and logical thinking, preparing them for more advanced mathematical concepts such as algebra and calculus.

In real-world applications, difference is used in various scenarios, such as calculating change in financial transactions, measuring quantities in recipes, and more. For example, if you have $9 and spend $5, the difference helps you determine that you have $4 left.
