Math problems rounding - Walking the ARE

So, I was looking at Walking the Are exam, and I got very close number to the one of the questions. It was asking "round to the nearest cent". When I looked at the answer, I saw that the rounding was also done during the math of things, but not only in the result, and that resulted very minor difference in my answer vs. the answer sheet. To my understanding, we should do the math without rounding to find the actual result/number, and should round to the nearest whatever after we find the result. How is NCARB doing these? Is my logic wrong, and should I round every number while doing the math? Because obviously because of this little difference, my answer was wrong, and I wouldn't want to do that in the real exam if my logic is wrong.

I really appreciate the response since this silly difference made me concerned! Thanks!!

Your logic is correct. But in my experience, you will not encounter calculations on the ARE where this even becomes an issue.

I agree. You typically work the #s in your calculator, don't clear the #s, do multiple operations, and round off the answer after the final math operation.

Rounding to the nearest cent would be unusual for construction. Rounded to the nearest dollar is much more likely for the ARE.

Hope this helps!
