Answers:
Put it into your calculator like this:

(15-5)/((12/(2*2))-2)

It's the brackets that is likely causing your problem--use nested parenthesis instead.

Use parenthesis instead of brackets:

(15 - 5) / (((12/2)*2) - 2)

... or you could just solve it "old school"
(15 - 5) / (((12/2)*2) - 2)
(10) / (6*2) - 2)
(10) / (12 - 2)
(10) / (10) = 1

Good luck in your studies,
