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) = 18RULES 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
