Subtraction is an arithmetic operation that represents the operation of removing objects from a collection. The result of a subtraction is called a difference. Subtraction represents removing or decreasing physical and abstract quantities using different kinds of objects including negative numbers , fractions , irrational numbers , vectors , decimals, functions, and matrices. Subtraction follows several important patterns. It is anticommutative , meaning that changing the order changes the sign of the answer.
First, we will see the meaning of subtraction. Then we will see methods for achieving it quickly. But in what is called the inverse of addition, we are given the sum and we have to name one of the two numbers. That has been called "subtraction. The historical name subtraction -- literally, "taken away from below" -- refers to a specific written method, namely writing the smaller number the subtrahend under the larger the minuend , and doing the method.
The problem of subtraction is to name the number we must add to the smaller number so that their sum will equal the larger number. How could you know that 12 minus 9 is 3? That is, you know elementary addition. We will now present two methods of written subtraction. One is the familiar subtraction by regrouping , or borrowing. The other is the less familiar but simpler method of adding to both numbers.
