Subtraction is a basic operation in mathematics, which refers to the process of subtracting one number from another. In subtraction, the minuend is the number to be subtracted provided in the subtraction problem, and the minuend represents the number to be subtracted. When we perform subtraction, we subtract the minuend from the minuend and get a value called difference. So subtraction is a poor process.

When we perform subtraction, we need to determine the number of times of subtraction. The number of subtractions refers to the difference obtained. The number of subtractions depends on the difference between the minuend and the subtraction. If the minuend is greater than the minuend, the difference may be positive. If the minuend is less than the minuend, the difference may be negative. Therefore, we must do proper subtraction to get the correct number.

Subtraction has many applications in daily life. For example, when we need to determine the elapsed time between two time points, we can use subtraction to obtain numbers. In this case, we can subtract the previous time point from the latter time point to get the elapsed time between these two time points. In addition, in business and finance, subtraction can be used to calculate the profit after income MINUS expenditure. These practical applications illustrate the importance of subtraction, because they are helpful to solve practical problems and make important decisions.
