In 1996, I wrote a simple calculator as study program. This is a calculator only for four basic operations (i.e., "+", "-", "*", "/"). However, it is different from normal calculators; it does not evaluate the expression until you enter "=". I feel relieved because I can find error inputs easier. JavaScript is now used everywhere, but I think this program is a more educational because it is simpler and you can see the behavior of this program more easily.
