In this example I commence with the farthings, and as the lower number is greater than the one above it, I borrow 4, the number of farthings in a penny, increases theto 5, from which I take 3, and have 2 left.

10 making it 11;

then carry one to 18, borrow 20 and 10 are 30; take 19 from 30 leaves 11; then carry 1 to the pounds, and proceed as in Simple Subtraction. Proceed in like manner in all cases in Compound Subtraction, observing to borrow as the rule directs.
