Distribution Property

Commutative Property of Addition

Answer 1

Which expression shows the result of applying the Commutative Property of Multiplication to the expression 4 • 5 • (3 + 1)?

4 • 5 • (4)

5 • 4 • (3 + 1)

4 • (5 • 3 + 1)

4 • (5 • 3 + 5 • 1)

Answer 2

Which expression will help make the following problem easier to solve using mental math? Arsha wants to buy 16 gallons of gasoline, which cost $2.10 per gallon.

e=1-1
e=0

Answer 5

When I have to drive a long distance to work, I am COMMUTing. Meaning that I move around. That's what it means in math too.

Answer 6

Identity Property \[a\star 0=a=0\star a\]
Associative property\[a\star(b\star c)=(a\star b)\star c\]
Distribution Property\[a\star(b+ c)=a\star b+ a\star c\]
Commutative Property\[a\star b=b\star a\]
