# Operations with Integers

### By: Melissa and Sebastian

## Adding

If the problem is 4+4=? and the digits are positive it will always be positive so its 4+4=8.

-8+4=? if one digit is negative and the other is positive it will always be negative so its -8+4=-4.

-9+-3=? if you have 2 negative numbers the answer will always be negative so its -9+-3=-12.

## Subtracting

If both signs are positive it will always be positive, 14 - (-6) = 20.

If both signs are negative it will always be negative. -12-6=-18.

Unlike signs like -4+3=? will always be negative, so the answer would be -1.

## Multiplying

The product of a positive integer and a negative integer is a negative integer. -3*5=-15.

The product of two negative integers is a positive integer. -6*-5=30.

If you have two positive integers is a positive integers 3*4=12.

## Dividing

If we have a negative and a positive for example -12/4=? the answer will always be negative so we divide and the answer is -3.

If we have negative divided by negative the answer will always be positive for example -4/-4= 1.

If we have positive divided by negative the answer will always be negative, ex. 8/-4= -2.
