- Whole numbers and numerators are entered as non-negative — a subtraction result that goes negative is reported via the separate "Result is negative?" flag, since the sign of a mixed number applies to the whole expression, not just its whole-number part.
Frequently asked questions
What is a mixed number?
A mixed number combines a whole number and a fraction, like 1½ (one and a half).
How do you add mixed numbers?
Convert each mixed number to an improper fraction (whole × denominator + numerator, over the same denominator), add them like regular fractions, then convert the result back to a mixed number.
What happens if subtraction gives a negative result?
The "Result is negative?" field shows "Yes", and the whole number and numerator shown represent the magnitude of the (negative) result.
