# Addition of integers

**Covid-19 has led the world to go through a phenomenal transition .**

**E-learning is the future today.**

**Stay Home , Stay Safe and keep learning!!!**

**Addition on number line :**

In order to add two integers on the number line, we follow the following method :

**Example 1 :**-3 + 4

1) Mark the first number on the number line, say -3.

2) The next number is + 4 ( Positive 4) so from -3 jump 4 steps to right and that gives you the answer.

So , - 3 + 4 = +1

**Example 2 :**4 + ( - 3)

1) First mark + 4 on the number line.

2) 2nd number is ( -3 ) so move 3 units to left from 4 and that gives you the answer.

**Rules for Operations on Integers :**

1) If two numbers have same sign then add them and give the common sign.

**Example :**1) + 5 + 8 = +13 2) – 6 – 8 = - 14

2) If two numbers have different sign then subtract them and give the sign of the bigger number.

**Example :**1) – 8 + 2 = - 6 2) – 7 + 15 = + 8 3) - 23 + 23 = 0

**Some solved examples :**Add the following :

1) -16 + 25

**Solution :**As the two numbers have different sign so subtract them and give the sign of the bigger number.

So, -16 + 25 = 9

2) -14 – 56

**Solution :**As the two numbers have same sign then add them ad give the common sign.

So, -14 – 56 = - 70

3) -16 + 23 – 12 – 8

**Solution :**

__-16 + 23__– 12 – 8

__+ 7 – 12__– 8

- 5 – 8

- 13
