SIMPLE MULTIPLICATION, TEACHETH to increase, or repeat the greater of two numbers given, as often as there are units in the less, or multiplying number; hence it performs the work of many additions in the inost compendious manner. The number to be multiplier is called the multiplicanu. 'The number you multiply by, is called the multiplier. The number found from the operation, is called the product. Note. Both multiplier and multiplicand are in general called factors, or terins. CASE I. RULE. Tultiply each figure in the multiplicand by the multiplier; carry one for every ten, (as in addition of whole numbers) and you will have the product or answer. PROOF.* EXAMPLES. What number is equal to 3 times 365 : Thus, 365 multiplicand. 3 inultiplier. CASE II. RULE. The multiplier being placed under the multiplicanu units under units, tens under tens, &c. multiply by each significant figure in the multiplier separately, placing the first figure in each product exactly under its inultiplier ; * Multiplication may also be proved ly casting out the g’s in the two factors, and setting down the remainders ; then multiplying the two remainders together; if the excess of 9's in their product is equal to the excess of e's in the total product, the work is supposed to be right, then add the several products together in the same ordet as they stand, and their sun will be the total product.
