... Suppose we wish to multiply 48 by 35 . If we first multiply 48 by 5 , we find 240 for the pro- duct ; if now we multiply this product by 7 , we obtain 1680 , which is evidently the same as 35 times 48 . Hence we infer this RULE ...

... Suppose we wish to know how many times 8 is contained in 32. We might proceed as follows : since 32 is greater than 8 , we know that 8 is contained in it , at least once ; therefore , subtracting 8 from 32 , we find 24 for a remainder ...

Σελίδα 111 - When a decimal number is to be divided by 10, 100, 1000, &c., remove the decimal point as many places to the left as there are ciphers in the divisor, and if there be not figures enough in the number, prefix ciphers.
Σελίδα 107 - To multiply a decimal by 10, 100, 1000, &c., remove the decimal point as many places to the right as there are ciphers in the multiplier ; and if there be not places enough in the number, annex ciphers.
Σελίδα 237 - If there be after payments made, compute the interest on the balance due to the next payment, and then deduct the payment as above ; and, in like manner, from one payment to another, till all the payments are absorbed ; provided the time between one payment and another be one year or more.

Σελίδα 108 - ... it follows, that in division the decimal places of the dividend must be equal to the number of places in the divisor and quotient taken together. Hence, the number of decimal places in the quotient must equal the excess of those in the dividend above those in the divisor.
Σελίδα 107 - In multiplication of decimals, we know that the number of decimal places in the product is equal to the sum of those in both the factors.
