Page 293 - In any proportion, the product of the means is equal to the product of the extremes.
Page 98 - Any term may be transposed from one member of an equation to the other, provided its sign be changed.
Page 295 - In any proportion the terms are in proportion by Composition and Division; that is, the sum of the first two terms is to their difference, as the sum of the last two terms is to their difference.
Page 291 - To express that the ratio of A to B is equal to the ratio of C to D, we write the quantities thus : A : B : : C : D ; and read, A is to B as C to D.
Page 48 - The same number, or equal numbers, may be added to both members of an equation without destroying the equality. 2.
Page 97 - Both members of an equation may be multiplied by the same number without destroying the equality.
Page 294 - If four quantities are in proportion, they are in proportion by inversion; that is, the second term is to the first as the fourth is to the third.
Page 88 - That is, the exponent of a letter in the quotient is equal to its exponent in the dividend minus its exponent in the divisor. For example, — = a*~".
