...Cube of 7 =343 Hence the following RULE. 1. Separate the given number into periods of three fgures **each, by putting a point over the unit figure, and every third figure beyond the place of units,** 3. Subtract the cube, thus found, from this period, and to the remainder bring down the next period;... | |

...and at least but two less. We therefore separate the given number into periods of three figures each, **putting a point over the unit figure, and every third figure beyond the place of units** ; thus, 46,656. We find by the table of powers, or by trial, the greatest power in the left-hand period,... | |
