Question

Mark wrote the highest score he made on his new video game as the product of 70 X 6000. Use the Associative and Commutative Properties to show how Mark can calculate this product mentally.

Answer 1

I think in commutative properties of multiplication:
70 x 6000 = 70 x 6000
420,000 = 420,000

I don't know associative properties, only commutative properties. Sorry :(

Answer 2

Mark wrote the highest score he made on his new video game as the product of 70 x 6000.

Associative property:

`70*6000`

`(7*6)*(10*1000)`

=>
`(42)*(10000)`

= 420000

Commutative property:

`(7*10)* (6*10*10*10)`

=
`7*6*10*10*10*10`

=
`42*10*10*10*10`

= 420000
