Numbers are the base of math. Any mathematical function includes numbers and their relationship with each other. Addition as the word literally means is nothing but adding something to one number(s) and then increasing its value.

The ‘+’ sign represents the plus sign. The sign responsible for increasing or adding more value to one number.

I – is one number

Step II

I – is another number

The two sets or groups of numbers are divided between ‘+’ sign.

So, | + | = | |

♣ + ♣ = ♣ ♣

This is not only limited to one single number on both the ends, but many numbers on both the sides.

Example 2 :-

♠ ♠ ♠ + ♠ ♠ = ♠ ♠ ♠ ♠ ♠

Now, replace the symbols by the number.

3 (as there are three spades, we write 3)

2 (as there are 2 spades, we write 2)

So, 3 + 2 = 5

So there are five (5) spades in total

The pictorial representation was just to make the concept of addition easier.

Example 3:- 1 + 2 = 3

[♥ + ♥ ♥ = ♥ ♥ ♥ ]

If same numbers are there on both the sides then,

5 + 5 = 10

[∗ ∗ ∗ ∗ ∗ + ∗∗ ∗ ∗ ∗ = ∗ ∗ ∗ ∗ ∗ ∗ ∗∗ ∗ ∗]

Now we will increase the value of number :-

7 + 8 = 15

(霴 霴 霴 霴 霴 霴 霴 + 霴 霴 霴 霴 霴 霴 霴 霴 = 霴 霴 霴 霴 霴 霴 霴 霴 霴 霴 霴 霴 霴 霴 霴]

1) 3 + 2 =

2) 5 + 4 =

3) 7 + 1 =

4) 6 + 6 =

5) 8 + 2 =

6) 9 + 1 =

7) 2 + 5 =

8) 1 + 2 =

9) 9 + 3 =

10) 8 + 5 =
