Good ideas =
A. Exercising after work
B. Eating ice cream at the end of a long day
C. Calling back the student you agreed to mentor (who left you a panicky voicemail) taking 30+ min to talk
Bad idea = [A + B + C / sleep] + needing to wake up at 5:45 am.
I feel that you wish to divide the quantity (A+B+C) by sleep , not divide C by sleep and then add to it A and B.http://en.wikipedia.org/wiki/PEDMAS
hence the need for sleep. You’re right, it should read [(A+B+C)/sleep] + need to wake up.
