One side of this folded paper sheet has a multiplication table for numbers from 1 to 50. The other side has instructions for using the table for both multiplication and division, a list of decimal equivalents of fraction, a table of squares, cubes, square roots and cube roots for numbers from 1 to 100, and a list of useful mathematical facts. One panel of the sheet is marked: MAGIC RECKONER and shows a rectangular base with a round scale and a round disc that rotates within the scale.

The Magic Reckoner was distributed with the Wizard Calculating Machine, an adder. For the adder, see 1980.0787.01.
