1
A dding two negative integers: add the absolute values the answer is negative Adding a negative and a positive number: subtract the absolute values the answer has the sign of the number with the larger absolute value Review Integer operations 1.) 6 + (-20) 2.) -8 + (-7)3.) -12 + 15

2
Rule: To subtract integers, add the opposite 4.) 12 (-3) 5.) -9 (-5) 6.) 14 20 7.) -18 30

3
When multiplying or dividing two integers with different signs the answer is always negative W hen multiplying or dividing two integers with the same sign the answer is always positive. 8.) 9(-3) 9.) (-12)(-2) 10.) 11.)

4
Evaluating Expressions To evaluate the expression, replace the variable with the given number. Be sure to use the proper order of operations Evaluate when x = 5 and y = 6. 1.)3x 3.)xy 2.) 12 + x + y 4.) 4y + 9 5.) 3y2 + 2x

5
Evaluate when a = -2 and b = 3 6.)6a + 2 = 7.) 9.) -8 + ab 10.) -a

6
Demonstrate Understanding 1.) 16 + (-9) 2.) -9 + 13 3.) 5 + (-5)4.) -2+ (-18) 6.) -2 - 13 5.) -34 - 12 7.) (-7)(-8) 8.) Evaluate each expression when x = 5 and y = -3 9.) 12 10.) 6(x+y) y 11.) 3y2 + 2x
