Place the sums or quantities as in compound Addition, with the less under the greater; then, beginning with the lowest denomination, subtract each under number from the one above it, and set down the remainder: but if the number of either denomination in the under sum be greater than the one above it, subtract it from as many of that denomination as will make one of the next higher, add the difference to the upper number, set down the amount, and carry 1 to the under number of the next higher denomination.
