Though both keypads actually have zero at the bottom, the remaining numbers go from top to bottom on the phone and bottom to top on the calculator. This is something that has puzzled lots of users including myself.

So, if you want to know the exact reason why the numbers on Calculators and phones are reversed, then we have to recall a story that begins back in pre-calculator days when there were mechanical cash registers.

Those cash registers carried “0” at the bottom, and the other numbers going up. Now you all might be wondered, why those cash registers were designed with “0” at the bottom. Well, this is because “0” is the most used number while making calculations and at that time it made complete sense to place it there because it’ an accessible to the fingers easily.

So, when mechanical calculators made their appearance, they followed the same trend as set by the cash register with 0 at the bottom and 9 at the beginning. Later, when hand-held and electronic calculators were invented, which we still use, they stuck with the same arrangement – 0 at the bottom, remaining numbers going from 1 in the bottom left corner to 9 in the top right corner.

So, basically, you can say that the number arrangements evolved from the cash register and the calculators still use the same pattern.
