# Integer Operations

### Addition, subtraction, multiplication, and subtraction

## Rules for addition

2.- If both signs are the same then you add and stay with the same sign.

3.- If they are different then you will subtract and stay with the sign of the highest number.

EXAMPLES:

-2+(-6)= -8

-4+6= 2

-6+(-12)= -18

## Adding Both signs were different, the first one positive and the other negative so we subtract and stay with the sign of the highest number in this case the 6 is the higher so the answer would be positive. | ## Adding Here the signs of both numbers are negative so we add and stay with the same sign so the answer would be negative because both signs are negative. | ## Adding Here in the first example is just common adding. Then in the other one there are different signs so we subtract and we stay with the sign of the highest number in this case -6 so the answer would be negative. And is the same in the next example. |

Then if you have like signs you add the numbers and stay with the sign.

Then if you have different signs you subtract and stay with the highest number sign.

Remember to change all the numbers to addition.

EXAMPLES:

-3-1= -4

-3-(-2)= -5

-5-4= -9

## Rules for multiplication

Then if they are like signs they stay positive.

Then if they are unlike signs the answer would be negative.

EXAMPLES:

-3*-2= 6

-4*-8= 32

-9*3= -27

## Rules for division

Then if they are like signs they stay positive.

Then if they are unlike signs the answer would be negative.

EXAMPLES:

-12/-3= 4

-45/5= -9

-25/-5= 5
