Rules and Definitions
What is absolute value?
The distance a number is from zero.
25 + 27 =
52
38 - 15
23
400
100 / 4 =
25
A negative + negative =
a bigger negative
-37 + (-13) =
(-50)
9 - (-20)=
29
8*(-4)
(-32)
8 / (-4) =
(-2)
Multiplying and dividing integers with the same sign will result in a ______ answer
positive
(-15) + 15 =
0
32 - (-14) =
46
-12 * 5 =
(-60)
-48 / 6 =
(-8)
2 rules for adding with different signs
bigger absolute value - smaller absolute value
keep sign of bigger absolute value
-12 + (9) =
(-3)
-20 - (-12) =
-8
5 * (-25) =
(-125)
-120 / -40 =
3
Multiplying and dividing integers with different signs will result in a ______ answer
negative
-49 - 22 =
(-71)
-13 * (-4)
52
-350 / 50 =
(-7)
