Somebody was worried about children not liking forth because the notation is different than they learned in school. My only experience is with HP calculators. My daughter had never seen anything but infix notation but she never questioned the postfix notation used by my HP-21. I showed her once how it worked ( she was about 10 years old ) and away she went. I know that for me it seems even more natural; an operation ( like + ) occurs when I push the '+' button rather than at some later time that I otherwise have to keep track of.

Even though we are taught to write equations infix, most people actually calculate using postfix -- we place the numbers on a stack and add them up: 125 50 + === 175
