Question

what is the value of 27-2m when m=3

Answer 1

$27 - 2(3) = \\ 27 - 6 = 21$
I think that is the answer.

Answer 2

The answer is 21.

If we're following the PEMDAS rule. We could make the equation: $27-2(3)$.

we would do multiplication first, which is $2(3)$. That leaves us with $27-6$.

Now we just subtract that to get our answer, 21.
