DAY 49:

Today’s Challenge

You roll two normal six-sided dice, both containing the numbers 1-6.  If you multiplied the two numbers that show, how many DIFFERENT answers is it possible to obtain?

The 7puzzle Challenge

The playing board of the 7puzzle game is a 7-by-7 grid of 49 different numbers, ranging from up to 84.

The 3rd & 7th rows contain the following fourteen numbers:

4   11   13   24   25   27   30   36   42   45   66   70   77   80

What is the sum of the factors of 90?
