Integers-
-number lines
-integer chips
-negative and positive numbers (-,+)
-zero pair
When subtracting something that isn't there, use a zero pair.
-6-(-4)= -2
-10+6= -4
6-7+2= 1
14-(-3)= +17
-3-(-7)= +4
-3-7= -10
3-7= -4
3+7= 10
-3+7= 4
Chapter 2- Multiplying Integers
Sign rules-
Even = When you have an even number of negative factors, the product is positive.
Odd= When you have an odd number of negative factors, the product is negative.
(+2) x (+3)= 2 groups of (+3)
(+2) x (-3)= 2 groups of (-3)
(-2) x (+3)= Remove 2 groups of (+3)
(-2) x (-3)= +6
Chapter 3- Dividing Integers
What is partitive division?
Partitive division is where you know the total number of groups, and you are trying to find the number of items in each group. (groups of)
6/2= 3
-6/(-2)= 3
What is Quotative division?
Quotative division is when you share between groups.
(-6)/2= -3
