As the mercantile method of proving addition is to reckon downwards, as well as upwards, the sums of which will be equal, when the addition is just, two spaces are left for the work.

SIMPLE SUBTRACTION

Teacheth to take a less number from a greater of the same denomination, and thereby to shew the difference.

SIMPLE MULTIPLICATION

Is a compendious way of adding numbers of the same name.
The amber to be multiplied is called the multiplicand.
Tac coer which multiplies is called the multiplier.
The aber arising from the operation is called the product

Teacheth to find how often one number is contained another of the same name.

e number given to be divided, is called the dividende number by which to divide, is called the dirige

The number of times the divisor is contained in the dividend, is called the quotient.

The remainder, if there be any, will be less than the divisor.

PROOF.

Multiply the quotient by the divisor; to the product add the remainder, and the sum will be equal to the dividend, il the work be right.

When the divisor is a compound number, that is, if any two figures, being multiplied together, will make that number, then divide the dividend by one of those figures, and the first quotient by the other figure, and it will then give the quotient required.-But as it sometimes happens that there is a remainder to each of the quotients, and neither of them, the true one, it may be found by

this

RULE. Multiply the first divisor by the last remainder, and the product add the first remainder, which will give the true
