Frequently asked questions
How do I enter a negative mixed number?
Choose minus, then enter nonnegative parts; −1 1/2 means −(1+1/2).
Is the result reduced?
No. The original denominator is preserved.
Must the fractional part be proper?
Usually yes; a larger numerator still evaluates as whole + numerator/denominator.
