Numbers that are multiplied to create a bigger number are called _______?
Factors
6 + 8 = 8 + 6
Commutative Property of Addition
Write an example of the Associative Property of Addition
Ex: (2 + 3) + 15 = 2 + (3 + 15)
3(x + 2) = 3x + 6
Distributive Property
(5 + 5) + 2 = 5 + (5 + 2)
Associative property of addition
6 x 0 = 0
Zero Product Property
3 ways to show the multiplication of 4 and 5
4 x 5
4(5)
4 ยท 5
16 x 1 = 16
Identity Property of Multiplication
6 x (4 x 3) = (6 x 4) x 3
Associative Property of Multicplication?
Find the next three numbers in this sequence: 1, 4, 9, 16 ...
25, 36, 49
1x1=1 2x2=4 3x3=9.....
a + (b + c) = (a + b) + c
Associative property of addition
9 x 1 = 9
Identity Property of Multiplication
Changing the order of the factors does not change the product.
True.
Commutative Property of Multiplication
2 - (4 - 3) = (2 - 4) - 3
SUBTRACTION IS NOT ASSOCIATIVE!!
Bonus Points: But which operations are..?
6 + 3 = 9
9 - 3 = 6
What does this show you?
That addition and subtraction are inverse operations. We can "undo" addition by subtracting one addend from the sum.
