Name: _____________________________Block:_____ Homework Integer Test Study Guide – Part 1 Absolute Value Absolute value is the distance of a number from zero on a number line. *A negative OUTSIDE the brackets means the answer will be _______________. *NO negative outside the brackets means the answer will be ________________. 1) −|21| 2) −|−9| 2 3) |− 5| 4) Using the number line below, plot all points that would have an absolute value of 7. Adding Integers *Same signs find the sum; Different signs find the difference. *Are there more positives or negatives? Use your + and - to help! 5) −17 + 5 6) 9 + (−4) 7) −9 + −5 8) 9) −21 + 6 10) 12 + (−15) −2 + (−7) Subtracting Integers *Rewrite using addition! Squeeze in the + after the first number and before the *a double – (-) becomes a big plus 11) 5 − (−4) 12) 4 − (−1) 13) 3 − 9 14) −4 − 7 15) 7 − 13 16) −3— 12 Multiplying and Dividing *Use the triangle of your answer or the tic-tac-toe board to help you remember the signs 36 17) (−3)(−7) 18) 20) −48 ÷ −8 21) 9(−6) 19) −5 ∙ 4 −6 22) Order of Operations Use PEMDAS to help you label and solve. 23) 4 + (8 − 2)2 ÷ −3 25) 4 + 18 ÷ (−5 + 8) − 20 24) 26) −20 + 42 ∙ 2 23 + 4 3−6 −81 −9
