Adding Integers
A positive number plus a positive number equals a
positive answer
(+21) + (+15) = (+36)
12 + 15 = 27Slide6
A
negative number plusa negative number is a negative
answer.
( - 5) + ( -8) = A
(-13) = ASlide7
If the signs are different
you subtract anduse the sign of the number with the largest absolutevalue.
12 + - 4 = 8
-15 + 11 = - 4Slide8

Answer
-4 = CSlide9
-8 + 3 =
- 5
-6 + -2 =
- 8
A = -7 + (12)
A = 5Slide10
A = - 7 + 13 + -5
A = 1
- 32 + 14 + 3 = X
-15 = X
Q = -8 + (-7) + (-3)
Q = -18
A = (-5) + (0) + (-5)
A = - 10Slide11
-7 + -7 =
0
35 + - 18 =
17
X = -7 + 15
X = 8
