Step-by-step explanation:

To remember the order of operations, it is best to use the PEMDAS acronym; Parenthesis, Exponents, Multiplications, Division, Addition, Subtraction.

A good way to remember this is with the phrase: Please Excuse My Dear Aunt Sally.

So, applying PEMDAS to your question:

3 - 9/(-1) * 3

We first need to divide 9 by -1

3 + 9 * 3

Then, we multiply 9 by 3

3 + 27

Finally, we add 3 and 27

30

Hope this helps.

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
