If it were by design, what would be the calculation order rule? It calculates 2*2^2+2 so that + has higher precedence than *. On the other hand, it calculates 2*2²+2, 2+2*2^2 and 2*2+2 so that * has higher precedence than +. This is a bug.

To recreate this bug, run "xcalc" from the command line, then type "2*2^2+2=". The result displayed should be "10", but instead it is "12". Note that "2+2*2^2=", "2^2*2+2=", "(2*2^2)+2=", and "2*(2^2)+2=" each give the correct result. My guess is that the program has problems when it must close two levels of implicit grouping at once. In effect, it treats the problematic input above as if it were "2*(2^2+2)=". This interpretation is consistent with other examples that I've tried.
