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
