It's interesting that there are different behaviors for 9^1/2 and 9^3/2 (as lurflurf points out).

Of course the problem with DWIM is that different people sometimes have different ideas about "meaning". Ideally, there should be a way to get the computer system to tell you exactly how it interpreted your input, e.g. by adding parentheses or whatever.

One good thing about Alpha is that it shows you "what it thought you meant" (in "pretty" form) as an intermediate step.

"In C there are 23 rules of precedence. The smart programmer knows that multiplication and division comes before addition and subtraction and then puts parenthesis around everything else".
