  2. Read the complete-set result rather than rounding upward.
  3. Choose Calculate & Save and compare the displayed result with the worked calculation.

Calculation and observed tool result

floor(10 ÷ 3) = 3 device sets; verify AAA alkaline against Three-cell equipment.

Recorded quantity: 10 cells.

What the result means

Three full sets fit with one cell left.

A mistake to avoid

A fourth complete set would require two more cells.

Limits of this example
