Note. Both multiplier and multiplicand are in general called factors, or terms. CASE I. RULE. PROOF.* Thus, 365 multiplicand. S multiplier. EXAMPLES. F CASE II. RULE. * Multiplication may also be proved ty casting out the e's in the two factors, and setting down the remainders ; then, multiplying the two remainders together; if wie excess of 8's in their product is equal to the ex ss of 9's in the total product, the work is supposed to be r. it. then add the several products together in the same order as they stand, and their sum will be the total product. EXAMPLES. What number is equal to 47 times 365 ? Multiplicand 3 6 5 14. Multiply 760483 by 9152. Ans. 6959940416. Ans. 2780206656. Ans. 195922095055, CASE III. When there are cyphers on the right hand of either or both of the factors, neglect those cyphers; then place the significant figures under one another, and multiply by them only, and to the right hand of the product, place as many cyphers as were omitted in both the factors. 7065000 X 870061465500000 749643000 x 695000=521001885000000 360000 X 1200000=432000000000 CASE IV. When the multiplier is a composite number, that is, when it is produced by multiplying any two numbers in the table together; multiply first by one of those figures and that product by the other; and the last product will be tire total required.
