18. Properties of Numbers and Number
Systems
Commutative (Addition and Multiplication)
When the order of 2 factors is changed the product is the
same (this also works for addition)
5 x 7 = 7 x 5,
5+7=7+5
35 = 35,
12 = 12
Associative (Addition and Multiplication)
When multiplying 3 or more factors, any of the two factors
can be multiplied, and the remaining factors may then be
multiplied without changing the product ( this also works
for addition)
(3 x 4) X 5 = 3 x (4 x 5),
12 x 5 = 3 x 20,
(3 + 4) + 5 = 3 + (4 + 5)
7+5=3+9
Math Concepts/Skills: Operations
Distributive
When multiplying the sum by a number is the same as
multiplying each addend by the number and then adding
the products
Identity
When multiplying any factor by 1, the product is the other
factor (when adding any number to 0 the sum is the other
number)
3 x (4 +2) = (3 x 4) + (3 x 2)
3 x 6 = 12 + 6
18 = 18
1 x 5 = 5,
0+5=5
Property of Zero
When multiplying any factor by 0, the product is 0
