Make sure you can find the Absolute Value of a Number
Adding IntegersSame Signs: Add the two numbers and use the same sign.
Different Signs: Subtract the two numbers, use the sign of the number with the larger absolute value.
Subtracting IntegersRule: Add the opposite of the second number.
(Make two marks.)
Multiplying/Dividing IntegersRule: + • + = +
+ • - = -
- • + = -
- • - = +
+ ÷ + = ++ ÷ - = -- ÷ + = -- ÷ - = +
