Why are keyboard numbers and phone numbers different?
One common explanation for the discrepancy between the phone and the calculator is that phone company engineers intentionally reversed the calculator layout because their research showed that people who were already adept at using a calculator punched the buttons too quickly for the telephone switching equipment to …
Why is the telephone touch tone keypad arranged differently from the calculator keypad?
It is pretty odd that a calculator and a touch-tone telephone have exactly opposite layouts for their keypads, which have many identical components. The telephone designers figured that if they reversed the layout, the dialing speeds would decrease and the tone-recognition would be able to do its job more reliably.
Why isn’t the number pad on the left?
Studies show that approximately 90% of the population is right-handed. Thus, to maximise its utility, numpad is placed on the right-hand side which is more convenient (closer) for the right hand. Placing numpad on the left-hand side would make it inconvenient for the right hand.

Why are the keypads on the calculator and the telephone the same?
It is pretty odd that a calculator and a touch-tone telephone have exactly opposite layouts for their keypads, which have many identical components. The reasons behind the differences are not known for certain, but a few theories exist. The first theory deals with the telephone’s circuitry and tone-recognition hardware.
Why do you put phone numbers in the bottom row?
Therefore it’s sensible to put digits 1, 2, and 3 to the bottom row, as it’s closer to the enter and also user reaches them easier. Since phone numbers are have limited number of digits and are in fact, randomly scattered, the Benford’s law doesn’t apply here, which means all the digits occur with similar frequencies.
