-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
