We all know numbers and how they work. We all use them. digits from 0-9. Grouped in groups of 10. Its a simple way of counting.
But, what if we used the alphabetical letters (A-Z) instead of the digits (0-9) we're used to?
To explain:
A is equivalent to 1, J is equivalent to 10, T is equivalent to 20, Z is equivalent to 26.
Now, If we were to increment Z by A (by one), then the result would be AA. That's right, there's no zero.
Now, ABC is equivalent to 731. Why is that so?
To explain:
The rightmost digit is multiplied by 1, the one to the left of that one is multiplied by 26, and the one to the left of that one is multiplied by 26 and multiplied by 26 again. ((1x26x26)+(2x26)+3 = 731)
I think this should get you an idea of how this works.
What's the equivalent to 0? i dunno, figure it out?
