To warm-up: Which 2-digit number is 1 more than a square and 1 less than a cube?
And a little bit harder: Can you find a three digit number which is 2 less than a cube and 2 more than a square?
Hint: the three digit number I can find is made of consecutive digits, like 567.
I'm posting one puzzle, riddle, math, or statistical problem a day. Try to answer each one and post your answers in the comments section. I'll post the answer the next day. Even if you have the same answer as someone else, feel free to put up your answer, too!
