How would I use Distributive property to rewrite each expression then solve

35 x 21

I hope that this is not another example of "silly math", but rather an exercise in doing mental arithmetic.

If it is the latter, I find value in that, and I would rewrite it as
35(20 + 1)
Now you should be able to do it in your head.

To use the Distributive Property to rewrite the expression and solve, you need to break down one of the numbers into its factors and distribute them to the other number.

Let's break down 35 into its factors:
35 = 7 x 5

Now, we can rewrite the expression using the Distributive Property:
35 x 21 = (7 x 5) x 21

Now, distribute the factors 7 and 5 to 21:
(7 x 5) x 21 = (7 x 21) + (5 x 21)

So, the expression is now simplified to:
35 x 21 = 147 + 105

Now, you can solve the expression:
147 + 105 = 252

Therefore, 35 x 21 = 252.
