Does anyone know the reason the key pad on a telephone is the exact opposite of a calculator keypad?

Kind of frustrating when you work in an office and are trying to use both at the same time.

Ha, when I was an Operator for Hyatt I dealt with that all the damn time.
I don’t know why, but I completely understand your frustration.

In 1960, when Bell labs was trying to figure out the best layout, they tested several possible configurations, including the standard adding machine layout. The layout we now have was chosen as representing the best combination of speed and user accuracy. Here’s a copy of the actual Bell Labs report describing the study.

@Harp and JP Thanks, both links were very infomative, though I thought the answer would be more clear cut.
