I did the problem but i want o check if I got the right answer .
isn't -54 point something?
Exponentiation first:
=> 42 / 21 * (-27) - (0.25)
Multiplication/Division left to right
=> 2*-27 - 0.25
=> -54 - 0.25
Finally, the subtraction. I get -54.25
Strange how 7 minutes have pasted and no one has answered this question. Anyways the answer is -54.25.
