Tracy,

If -2^2 is read as anything other then "raise negative two to the second power" it is wrong. There are two operands and one operation in the phrase. Operand1: negative two (written as -2), Operand2: 2, Operation: exponentiation.

I don't have control over any of the programming languages that interpret that as "negate two to the second power" they have implemented an incorrect algebraic parser if they do.

If they give a different result than they give for -2 * -2 they are wrong.
