1) Match the term with their appropriate definition:
_________: Integer a. The opposite of a number, Ex. 10, -10
_________: Additive Inverse b. A statement that two ratios are equivalent
_________: Unit Rate c. A positive or negative whole number
_________: Proportion d. The distance from zero on a number line, |−𝒙|
_________: Absolute Value e. A ratio with a denominator of equal to 1
2) Circle the number in each set with the highest absolute value: a.
10, -2, 15 b.
-1, 0 , -11 c.
-100, -101, 102

Adding Integers
With the same sign ( ++ or --)  keep the sign and add absolute values of each integer
“SSA- Same Signs Add”
With different signs (+- or -+)  Take sign of the larger absolute value and subtract absolute values
“DSS- Different Signs Subtract”
