# Why postfix is used more often than prefix expression?

i was reading stack and i came across the infix, preifx and postfix expression.So i understood that why postfix /prefix expressions are preferred over infix expression ( due to its unambiguous nature) .But i am not getting any enough information about the popularity reason of postifx expression over prefix expression.

Why are we not using prefix expression than the postfix expression more often?

I am guessing that ,

1. it's related to the easiness of converting the infix to postfix
2. or the evaulation process of postifx is easy than prefix.

If so, Please someone elaborate on it.

thanks.

• The only reason I am aware of is, "because HP made a bunch of calculators that used postfix notation." – Aaron Rotenberg Mar 25 '20 at 17:48

• operator -> get from the stack the number of values it needs (two for +, three for ?:, one for unary - and so on), combine the values using the operator and put the result on the stack.
