What will I learn?
Solving this puzzle validates that you can manage string manipulation (split, concatenation, conversion), array arithmetics. You may discover the vigesimal (base twenty numeral) system.
The goal of this puzzle is to make you compute an arithmetic operation from two mayan number. This puzzle make you discover computation in base 20 (used by mayans). It will make you play a lot with string to digits conversions and mechanics to store their values in associative arrays.
