Proceeding to the shillings, we cannot take 14s. from 4s., but we bor. row 1 from the pounds =20s.; and 14s. subtracted from £ 20s. leave 6s., to which we add the upper number, 4s. making 10s., which we set down. Proceeding to the pounds, we carry 1 to £5 makes £6, which subtracted from £30 leave £24, and the work is done. d. £ S.. d. d. qr.
