comment Signed binary arithmetic
I guess I'm doing binary addition wrong because I'm just not getting -22.. When you have 1 + 1 = 2 = 10 binary, you place 0 and carry the 1. When you have 1 + 1 + 1 = 3 = 011, I thought you place 0 and carry each 1 two the next 2 places? Update: Confirmed, I've been doing it wrong.

comment Probability of getting 5 multiple-choice questions answered correctly
no total number of questions were of concern in the question. Maybe a total of 5? I got the same answer as above, so I guess I'll stick with that in the future when it is the case.

Thank you for the clarification

If I understand this correctly, you are using the min range and max range and given the integer value, use what product to equal those ranges, then subtracting those products to get the number between the min and max range?
