-39 Use the order of operations and integers to solve.

Explanation:

The way the students of Carr Junior High in Santa Ana CA remember the order of operations is as follows.

If you get hurt in PE call an MD Asap ( call a doctor as soon as possible)

P states for parenthesis so do the work inside of the Parenthesis first.
E = exponents there are no exponents in this expression.

( 5+ 9 -1) ASap A = addition S = Subtraction. ( As soon as possible is one time not two, so do Addition and Subtraction at the same time working from left to right )

5+ 9 -1 = 14 -1

14 -1 = 13

so after removing the first parenthesis gives

13 xx ( -3) MD is a doctor one person not two, so do multiplication and division at the same time working from left to right.

13 xx ( -3) = - 39

A positive times a negative is a negative.
a negative ( taking way) something good ( a positive) is bad ( negative)
