As a professional cartographer, I can only assume that the correct answer is a map of Cleveland.

sounds legit


I know it sounds off, but I'm referring to the actual action taken.

Multiplication and Division are one another's inverses.

Multiplication by X is Division by 1/X.

Therefor you do not put Multiplication before Division, because they can be substituted.

PEMDAS
Parentheses
Exponent
Multiplication OR Division
Addition OR Subtraction

The ones on the same line are just different forms of the same equation 1/4=1x.25

Thus making this
(12/4)x3
Or if we are going from the thread that closed
12/4(1-4)
It would be

12/4x(-3)
3x(-3)
-9

Sure.

-9 = 12 / 4(1-4)

-9 = 12 / 4(-3)

-9 = 12 / 4 * -3

-9 = 3 * -3

-9 = -9

There. Done.
