This subtraction sum may be very neatly worked, without reducing the distances to inches, thus:—
| miles | furlongs | rods | yards | feet | inches | |||||||
| 1 | „ | 0 | „ | 0 | „ | 0 | „ | 0 | „ | 0 | ||
| 7 | „ | 39 | „ | 5 | „ | 1 | „ | 5 | ||||
| 0 | „ | 0 | „ | 0 | „ | 0 | „ | 0 | „ | 1 | ||
Instead of borrowing one foot, we borrow half-a-foot—i.e., 6 inches; taking 5 from the 6 we have 1 as a remainder; now carrying the 6 inches to the 1 foot, and borrowing half a yard, and subtracting, we have 0 as remainder; carrying the half-yard to the 5 yards, we borrow the full 51⁄2 yards, which are one rod, and proceed in the usual manner afterwards, with the result that is shown.
