Σελίδα 136 - Multiply each payment by its term of credit, and divide the sum of the products by the sum of the payments ; the quotient will be the average term of credit.
Σελίδα 148 - Multiply the divisor, thus augmented, by the last figure of the root, and subtract the product from the dividend, and to the remainder bring down the next period for a new dividend.
Σελίδα 100 - To reduce a whole number to an equivalent fraction, having a given denominator. RULE. Multiply the whole number by the given denominator, and place the product over the said denominator, and it will form the fraction required.
Σελίδα 104 - It will be seen that we multiply the denominator of the dividend by the numerator of the divisor for the denominator of the quotient, and the numerator of the dividend by the denominator of the divisor for the numerator of the quotient.
Σελίδα 149 - Subtract the cube of this number from the first period, and to the remainder bring down the first figure of the next period for a dividend.
Σελίδα 115 - Sir," said I, after puzzling a long time over "more requiring more and less requiring less" — "will you tell me why I sometimes multiply the second and third terms together and divide by the first — and at other times multiply the first and second and divide by the third?" "Why, because more requires more sometimes, and sometimes it requires less — to be sure. Haven't you read the rule, my boy?" " Yes, sir, I can repeat the rule, but I don't understand it.
Σελίδα 147 - ... and to the remainder bring down the next period for a dividend. 3. Place the double of the root already found, on the left hand of the dividend for a divisor. 4. Seek how often the divisor is contained in the dividend...
Σελίδα 154 - GEOMETRICAL PROGRESSION. A series of three or more numbers, increasing by a common multiplier, or decreasing by a common divisor, is called a geometrical progression. If the greater numbers of the progression are to the right, the progression is called an ascending geometrical progression, but, on the contrary, if they are to the left, it is called a descending geometrical progression. The number by which the progression is formed, that is, the common multiplier, or divisor, is called the ratio.
