- In pure algebra Descartes expounded and illustrated the general methods of solving
**equations**up to those of the fourth degree (and believed that his method could go beyond), stated the law which connects the positive and negative roots of an equation with the changes of sign in the consecutive terms, and introduced the method of indeterminate coefficients for the solution of**equations**.' - Energyequations, such as the above, may be operated with precisely as if they were algebraic
**equations**, a property which is of great advantage in calculation. - Among the great variety of problems solved are problems leading to determinate
**equations**of the first degree in one, two, three or four variables, to determinate quadratic**equations**, and to indeterminate**equations**of the first degree in one or more variables, which are, however, transformed into determinate**equations**by arbitrarily assuming a value for one of the required numbers, Diophantus being always satisfied with a rational, even if fractional, result and not requiring a solution in integers. - Often assumptions are made which lead to
**equations**in x which cannot be solved "rationally," i.e. - The distribution of weight in chemical change is readily expressed in the form of
**equations**by the aid of these symbols; the equation 2HC1+Zn =ZnCl2+H2, for example, is to be read as meaning that from 73 parts of hydrochloric acid and 65 parts of zinc, 136 parts of zinc chloride and 2 parts of hydrogen are produced.
