Zero pair is:
6 -6 = 0
6 -6 = 0
10 -10 = 0
11 -11 = 0
14 -14 = 0
63 -63 = 0
-When Subtracting something that isn't there, use a zero pair.

Integer examples
without pictures
without pictures
-6 - ( -4) = -2
-10 +6 = -4
6 -7 +2 = 3
4 - ( -3) = 11
with pictures
+3 + (-7)= -4
-3+(-7) = -10
-3 +7= 4
3 +7= 10
You try;
-7 -2 =
-7 -2 =
5-(-1)=
10 -3=
14 - (-9)=

Chapter 2 "Multiplying Integers"
(+3) x (+2) or make 3 groups of +2
(+2) (+2) (+2) = (+6)
or you can also have repeated addition (2+2+2 ) =6
(-2) x (+3) or 3 x -2 = -6
remove 2 groups of +3
(+2)x (-3)
2 groups of (-3)
Applying the sign rule
(-2) x (-3)
remove two groups of -3
Here is where we apply the sign rule
Here is where we apply the sign rule
When you have and even number of negative factors
the answer is POSITIVE
The answer is 6
(-2) x (+3)= -6
Remove 2 groups of positive 3
Sign Rule
When you have an odd number of negative factors
the answer is NEGATIVE
You try;
(+4)x (+2) =
(+5) x (-2)=
(-4) x (+2) =
(-6)x (-1)=
Heres a video about "Multiplying integers"
There are two types of Division
Partitive Division or making parts/groups of
+6 ÷ +3 =
how many groups of +3 are there in +6 ? 2
(3x2=6)
(6÷3=2)
(2x3=6)
(6÷2=3)
There are 2 +3's in +6
Quotative Division or sharing your total with groups
+6 ÷ +3
