MULTIPLICATION. 43
cipher on the right of 24, which is the multiplicand. each figure is removed one place to the left, and its val- we is increased ten times, or it is multiplied by ten. By attaching two ciphers each figure is removed two places to the left, and its value is increased one hun- dred times, or it is multiplied by 100.
Rule..—Write on the right of the multiplicand, as many ciphers as there are in the multiplier. The num- ber so formed will be the required product.
EXAMPLES FOR PRACTICE.
2. Multiply 4256 by 10. Ans. 42560.
3. Multiply 6542 by 100. Ans. 654200.
4. Multiply 8954 by 1000. Ans. 8954000.
5. Multiply 25563 by 10000. Ans. 255630000.
$ 40. When the multiplier is any number other than one, with ciphers attached on the right, proceed thus:
1. There are 365 days in a year. How many days in 30 years?
Ans. 10950 days.
OPERATION. Multiply 365, the multipli- Multiplicand 365 cand, by 3 the significant fig- Multiplier 30 ure of the multiplier, which - gives the product 1095. To Product 10950 the right of this attach the ci- pher of the multiplier, which gives 10950, which is the product sought. 2. In one year there are 365 days. How many days in 3400 years. Ans. 1241000. OPERATION. Multiply 365, the multi- Multiplicand 365 plicand, by 4 the right hand Multiplier 3400 significant figure of the mul- tiplier, then by 3 the next 1460 significant figure. This 1095 gives the product 12410. On the right of this product Product 1241000 attach the two ciphers of the multiplier, which gives 1,- 241,000, the product required.
