5 x 1 x 11 x 4
Look for multiplying numbers together that end up being multiples of 10; 5*4 = 20, so using the associative property
5 x 1 x 11 x 4 = (5 x 1 x 11) x 4
Using the commutative property:
= 4*(5 x 1 x 11) = 4*5 x 1 x 11 =
(4*5) x (1 x 11) = 20 * 11
Factoring the 20:
= (2*10)*11
Using the commutative property, and then associative property:
= 11*(2*10) = (11*2)*10 = 22 * 10 = 220
