3. Subtraction. 149. 1. A person bought a cow for £3 7s. 6s., and sold it for £4 12s. Sd., how much did he gain

We write the less number under the greater, so that £

pence shall stand under pence, shillings under sbil4 12 3 lings, and pounds under pounds; we then begin at

the right hand, but as we cannot take 6d. from 3d.,

we borrow from the 12s. Is.=12d., which we join with Gain 1 9 the 3d., making 15d., and then 6d. from 15d. leaves

9d., which we write under the pence. We now proProof 4 12 3 ceed to the shillings, but as we have borrowed ls. from

12s. we call the 12s. 11s., and 7s. from 11s. leaves 48., and lastly, £3 from £4 leaves £1. Thus we find that he gained £1 4s. Id. The above process is called Compound Subtraction.

COMPOUND SUBTRACTION 150. Is the taking of one compound number from another, so as to find the difference between them. (42)

RULE. 151. Write the less number under the greater, so that the parts which are of the same name may stand directly under each other.

Begin with the lowest denomination, and take the number in the lower line from the one standing over: proceed in the same way with all the denominations.

Should the number in the upper line be less than the one standing under it, suppose as many units to be added to the upper number as will make a unit of the next higher denomination, remembering to diminish the number in the next place in the upper line by 1.

PROOF.—The same as in Simple Subtraction.
