Addition and subtraction are the two primary arithmetic operations where we learn to add and subtract two or more numbers or any mathematical values. The other two basic math operations are multiplication and division. The symbol to represent addition is ‘+’ (plus sign) and subtraction is ‘-’ (minus sign).
Both addition and subtraction are inverse operations of each other. For example, if 9 + 1 = 10, then 10 – 1 = 9. That shows if 1 is added to 9 then the result is 10, whereas if 1 is subtracted from 10, then the result is 9. What is Addition? Addition means summing up two or more numbers or values to get another number. For example, if we add 2 and 3, we get 5 as the result.
2 + 3 = 5
Now, let us understand the sum of 2 and 3 practically. Suppose, we have 2 apples in a basket and 3 more apples are added in the same basket, so how many apples are there altogether?
2 → 1 + 1
3 → 1 + 1 + 1
2 + 3 = 1 + 1 + 1 + 1 + 1
Now if we count each apple, then it is equal to 5.
The property of addition is to increase the value by adding another value to it. What is Subtraction?
Subtraction means reducing a value from another value to get the required value.
For example, subtracting 3 from 5 gives 2 as the answer.
5 – 3 = 2
Now, if we imagine, there are 5 apples in a basket and we take out 3 apples from the basket, then how many apples are left?
The answer is 2 apples.
5 – 3 = 1 + 1 + 1 + 1 + 1 – 1 – 1 – 1 = 2
