What this calculator does
Find the exact arithmetic mean of a list of integers, fractions, or mixed numbers.
How it works
The calculator evaluates average = (x₁ + x₂ + … + xₙ) ÷ n. Inputs are checked before calculation, and invalid values such as zero denominators or out-of-range selections produce a clear error instead of a misleading result.
Input query strings and outputs
