# How do you use the order of operations to answer 18200xx100-:91000?

The answer $20$.

#### Explanation:

Since you are only multiplying and dividing, you complete the operations as you move from left to right.

First
$18 , 200 \times 100 = 1 , 820 , 000$

Second
$1 , 820 , 000 \div 91 , 000 = 20$

I found $20$
$18 , 200 \cdot \frac{100}{91 , 000} =$
$= 18 , 2 \cancel{00} \cdot \frac{100}{91 , 0 \cancel{00}} =$
$= 182 \frac{10 \cancel{0}}{91 \cancel{0}} = \frac{1820}{91} = 20$
