The operands may be either variables or expressions of the         same type or of different type.        Warning: If p > 2^30, the primality of p is not tested.                Example 1: (correct)                (log2(123/45)/gcd(24,76)) + 17896785235/(1/3)        Example 2: (correct)                3 / NF(A^2 - A - 1)        Example 3: (correct)                (x^2 + y*z) / (x/y)        Example 4: (correct)                {{x, y} {x - 1/2, 3}} / {{1, 2} {4, 5}}        Example 5: (correct)                0.2 / (3 + 3e-10)
