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

Aug 10, 2016

#### Answer:

$85 , 000$

#### 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.

$10 \times 5 \times 85 \times 20 = 85 \times 10 \times 20 \times 5 = 20 \times 85 \times 5 \times 10$

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

$\textcolor{red}{\left(20 \times 5\right)} \times 10 \times 85$

=$\textcolor{red}{100} \times 10 \times 85 = 85 , 000$
