Identity Property
The product of 1 and any number 4 ๎1 ๎4
equals that number. 1 ๎4 ๎4
Zero Property
The product of 0 and any number 0 ๎2 ๎0
equals 0. 2 ๎0 ๎0
Commutative Property
You can multiply two factors in any 3 ๎4 ๎12
order and get the same product. 4 ๎3 ๎12
Associative Property
You can group factors in different ways (3 ๎2) ๎4 ๎3 ๎(2 ๎4)
and get the same product. 6 ๎4 ๎3 ๎8
24 ๎24
Distributive Property
You can think of one factor as the sum 4 ๎6 ๎4 ๎(1 ๎5)
of two addends. Multiply each addend ๎(4 ๎1) ๎(4 ๎5)
by the other factor and add the products. ๎4 ๎20
๎24
