# Operations with integers

### Adding, Subtracting, Multiplying and Dividing integers

## Adding and Subtracting Integers

Unlike signs subtract and stays with the sign of the bigger number and like signs add and stay with the signs.

(Two positive make a positive, two negatives make a positive, one positive and one negative make a negative and one negative and one positive make a negative.)

Adding

example 1. -7+-2= -9

example 2. 9+-13= -4

example 3. 8+-17= -9

Subtracting

example 1. 8-(-9)= 17

example 2. -7-9= -16

example 3. 4-10= -6

## Multiplying and Dividing Integers

Unlike signs give you a negative answer and Like signs give you a positive answer.

example 1. -3x-2= 6

example 2. -5x9= -45

example 3. -6x6= -36

example 1. -12/ 3= -4

example 2. -20/4=-5

example 3. -36/4= -9
