Adding Integers
6 + (-1) =
5
2 - (-9) =
11
-8 x 6 =
-48
56 ÷ (-8)
-7
What are the rules for Subtracting Integers
Hint: 3 Words
Same Switch Switch OR Keep Change Change
3 + (-12) =
-9
1 - (-17) =
18
10 x (-9) =
-90
-81 ÷ -9 =
9
Is the answer positive or negative when multiplying two numbers with the SAME symbol. (both numbers are positive OR both numbers are negative)
Positive ALWAYS Positive
-2 + 5 =
3
-8 - (-13) =
5
-7 x (-12) =
84
-15 ÷ 3 =
-5
Is the answer positive or negative when multiplying two numbers with DIFFERENT symbols. (one number is positive and the other is negative)
Negative ALWAYS Negative
-13 + (-4) =
-17
-11 - (-6) =
-5
11 x (-14) =
-154
-100 ÷ -10 =
10
Solve the Equation:
3 + (-3) - 2 =
-2
-71 + (-29) =
-100
4 - 16 =
-12
-23 x (-24) =
552
-150 ÷ -15 =
Solve the Equation:
(-100) x 6 - 1=
-601
