![](/common/images/spacer.gif) The Mathematica functions Positive, Negative, and NonNegative evaluate for numbers only. They can be used to define properties of symbols but for combinations of such symbols, the properties are not evaluated any further. The function NonNegativeQ tries to find out if the result cannot be negative. In such cases, it returns True, otherwise False.
