# Rules for Operations with Integers

### By: Vladimir Hernandez and Alysa Pérez

## Rules for Adding with Integers

Examples:

1 + (-3) = 4

2 + 3 = 5

-3 + 4 = 1

## RULES FOR SUBTRACTING WITH INTEGERS

Examples:

1-. 14 - (-6) = 20

2-. 5 - (-2) = 7

3-. 12- (-6) = 18## RULES FOR MULTIPLYING WITH INTEGERS

Rule: To multiply or divide signed integers, always multiply or divide the absolute values and use these rules to determine the sign of the answer: The product of two positive integers or two negative integers is positive. The product of a positive integer and a negative integer is negative.

Example:

3 x -6= -18

4 x 4= 16

- -4 x 6= -24

## RULES FOR DIVIDING WITH INTEGERS

Rule: Division of Integers is similar to division of whole numbers (both positive) except the sign of the quotient is determined.

Example:

3 x -6= -18

4 x 4= 16

- -4 x 6= -24
