”εκΏδα 87 - The greatest common divisor of two or more numbers is the greatest number that will divide each of them without a remainder. Thus 6 is the greatest common divisor of 12, 18, and 24.
”εκΏδα 265 - Find the amount of each payment from the time it was made to the time of settlement. III. Subtract the sum of the amounts of the payments from the amount of the principal, and the remainder will be the sum due.
”εκΏδα 355 - A Circle is a plane figure bounded by a curved line every point of which is equally distant from a point within called the center.
”εκΏδα 336 - The square described on the hypothenuse of a rightangled triangle is equal to the sum of the squares described on the other two sides.
”εκΏδα 347 - That is, the first term of an increasing arithmetical series is equal to the last term diminished by the product of the common difference into the number of terms less one.
”εκΏδα 148 - 03, the same as before. IT 73. The foregoing examples and remarks are sufficient to establish the following RULE. In the division of decimal fractions, divide as in whole numbers, and from the right hand of the quotient point off as many figures for decimals, as the decimal figures in the dividend exceed those in the divisor, and if there are not so many figures in the quotient, supply the deficiency by prefixing ciphers.
”εκΏδα 184 - The terms folio, quarto, octavo, duodecimo, etc., indicate the number of leaves into which a sheet of paper is folded. A sheet folded in 2 leaves is called a Folio.
”εκΏδα 333 - Subtract the square number from the left hand period, and to the remainder bring down the next period for a dividend. III. Double the root already found for a divisor...
”εκΏδα 307 - Then multiply the second and third terms together, and divide the product by the first term: the quotient will be the fourth term, or answer.
”εκΏδα 59 - PROOF. Multiply the divisor and quotient together, and to the product add the remainder, if any; if the result be equal to the dividend, the work is correct.
