Okay, it's been a while since I've done simple subtraction, so I've forgotten the rule about subtracting from zero and watnot. Anyway, that's just the simple problem.

Here's the real issue: I had an interview for a job that requires me to count back change (because they DON'T use cash registers, Bruster's IceCream). So I have 1 day to tighten up to go back to take a test. After coming home to practice, I've found out that today that I'm pretty dumb

Anyway, I understand the general concept of counting back change. However, I don't know the steps to actually perform this task.

Can anybody help me? Explanations... Exercises... anything?

Keep in mind, I'm pretty dumb xD

If customer pays 50.00 and it costs $44.03. The change is $5.97 (I used calculator). How am I supposed to count that back? Any tips on what I'm supposed to do to get the exact change?

For example though, the realistic prices are like... $2.71 and $3.99

Random tidbit, tax is 6% where I live... If anybody wants to know xD

I think this is an article that explains what I'm supposed to be doing, I just don't really get it xD
