Excel Math Bug
By the definition of unary minus, -x^2 is the number such that x^2 + (-x^2) = 0. Without a citation to "the definition" you're using, this is not persuasive. Your statement begs the question of operator precedence, and using it to argue for a particular order of precedence is therefore a tautology. Pick *any* algebra text, calculus text, etc. The expression -x^2 means the negative of x^2 throughout mathematics. If you want the negation to have priority, you write (-x)^2. For example, if you see the expression -x^2 +3x-2 in any math book, it means (-1)*x^2 +3*x -2 and is certainly not the same as x^2 +3x-2 (unless you are in a field of characteristic 2). This is absolutely standard notation. --Dan Grubb |
