# How do you evaluate 4-3(7-(2*3))?

Jul 6, 2017

Use the order of operations.

#### Explanation:

My students at Carr Elementary School in Santa Ana came up with this way of remembering the order of operations

" If you get hurt in PE call a doctor MD as soon as possible Asap"

$4 - 3 \left\{7 - \left(2 \times 3\right)\right\} = 4 - 3 \left(7 - 6\right)$ continue with removing ( )
$4 - 3 \left(7 - 6\right) = 4 - 3 \left(1\right)$ next call a doctor MD a doctor is one person so do multiplication and division as the same time working from left to right
$4 - 3 \left(1\right) = 4 - 3$
$4 - 3 = 1$
