Mark wrote the highest score he made on his new video gameAs the product of 70*6000 use associative and communicative properties to show how mark can calculate. His product mentally

The correct answer is:

We can use the associative property to write 70 as 7*10. We can do this same process to write 6000 as 6*1000. This gives us:

(7*10) * (6*1000)

Using the commutative property, we can rearrange the factors of this problem

(7*6) * (10*1000)

7*6 is in our multiplication tables, and we know that powers of 10 allow us to just add the correct number of zeros. This means we would have 7*6=42, and have 4 zeros, for 420000

70*6000

7*6=42

then add the 4 zeros

70*6000=420000
