You're given a graded series of number puzzles. They start real easy and
then quickly adapt to your skill level. Going from easy additions to negative numbers,
decimals, fractions, Roman numerals etc. You have 10 minutes to get as far as you can
but you'll have a min deducted for using Give Up and 30 sec deducted for using Help.
You'll be given a grade at the end. Press Restart when you're ready. Good Luck !
