Question

How do you simplify `(10times5) times (85times20)` using PEMDAS?

Answer 1

`85,000`

Explanation:

This is not really a question requiring PEDMAS, or any order of operations, because there is only multiplication.

The brackets have no effect at all and the numbers can be multiplied in any order, as long as each is used only once.

`10xx5xx85xx20 = 85xx10xx20xx5 = 20xx85xx5xx10`

But by grouping them first we can make the multiplication easier for ourselves.

`color(red)((20xx5))xx10 xx85`

=`color(red)(100) xx 10 xx 85 = 85,000`
