ZERO.
To add up certain.numbers in different groups within, what is • known as a magic square, and find in' each in': stance, the result to be zero, might seem at first to be somewhat perplexing, but a little thought will reveal that it is not difficult to discover such an arrangement of figures. But here is one that will require a little ingenuity to find, being subject to specific conditions, and on that account somewhat different to a "fraction" square originated by that figure genius \V. Beyre. The problem is to arrange the figures in a nine square, using any digits and the ciph- if desired (at least one of the digits to be repeated), so that a combination of four numbers in symmetrical form will add up zero in not fewer than as many ways as there are small squares. Decimate and fractions are not allowed. A feature of one arrangement in mind of this, character is the uniform value-order of the figures, comprising the whole square. Can the reader arrange one under these conditions?
