5 points for each problem.

For the last question, I just skimmed over what you had and didn't really
check that it was correct.  I took off a point or so if you were pretty 
brief.

For totalNums, -1.5 if it is mostly correctly but crashing due to an error
such as trying to convert an empty string to float or int.

-1 on totalNums if adding up all the digits, so 15 would is giving 6.
