DAY 173:

Today’s Challenge

When allocating each letter of the English alphabet a numerical value as follows; A=1 B=2 C=3 … Z=26, the value of the word SUM, for example, would be 19+21+13 = 53.

What would be the value of my popular number puzzle, MATHELONA?

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.

6    7    13    16    21    25    36    42    45    50    66    80    81    84

Find three pairs of numbers that have a sum that is also on the list.
