COMPOUND SUBTRACTION. Compound subtraction teaches to find the difference between any two sums or quantities, which consist of several denominations.

RULE. Place the sums or quantities as in Compound Addition, with the less under the greater; then, if the numbers of the several denominations in the under sum, be not greater than those of the same denomination in the upper sum, begin with the lowest denomination, and subtract each under number from the one above it, setting down their respective remainders : but if the number of either deno. mination 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 I to the under number of the next higher denomination.

Proof: as in Simple Subtraction.
