Σελίδα 164 - PROBLEM II. The first term, the last term, and the number of terms given, to find the common difference. RULE. — Divide the difference of the extremes by the number of terms less 1 , and the quotient will be the common diffcrenct.
Σελίδα 62 - Multiplying or dividing both terms of a fraction by the same number does not change its value.
Σελίδα 51 - When the numerator is less than the denominator, the value of the fraction is less than 1.
Σελίδα 124 - The rule for casting interest, when partial payments have been made, is to apply the payment, in the first place, to the discharge of the interest then due. If the payment exceeds the interest, the surplus goes towards discharging the principal, and the subsequent interest is to be computed on the balance of principal remaining due.
