# Operations With Integers

### Adding, Subtracting, Multiplying, and Dividing Integers

## BY- Jose Alberto Recio, Luis Salas

## Adding Integers

1- If the numbers have the same sign you need add them

2. if the numbers have different sign subtract

examples-

same sign-

6+2= 8

-4+(-3)= -7

different sign-

8+(-3)= 5

-9+4= -5

## Subtracting Integers

1- when you are subtracting forget the sign and subtract as usual then put the sign or the larger number

2- When you have 2 minus sign together it converts to a plus sign

examples-

4-(-8)= 12

-9-4=- 13

## Multiplying Integers

1- the product of two integers with same sign is positive

2- the product of two integers with different sign is negative

examples-

same signs

2x3= 6

-4x-6= -24

different signs

8x-4= -32

-2x7= -14

## Dividing Integers

1- the quotient of two integers with the same signs is positive

2- the quotient of two integers with different signs is negative

examples-

same signs-

32/4= 8

-8/-2= 4

different signs

40/-8=5

-50/10= -5
