Subtracting is a basic mathematical operation that involves taking one number away from another. The result of this operation is called the difference. For example, if you have 5 apples and you subtract 2 apples, you are left with 3 apples. This process helps us understand how much is left after removing a certain quantity. In everyday life, subtraction is used in various situations, such as calculating expenses or determining how much time is left until an event. It is an essential skill for problem-solving and decision-making, making it a fundamental concept in both mathematics and daily activities.
