In mathematics, geometric measure theory (GMT) is the study of the geometric properties of the measures of sets, including such things as arc lengths and areas. It uses measure theory to generalize differential geometry to surfaces with mild singularities called rectifiable sets. It has applications in various areas, including image processing and fracture mechanics.

A mathematical means of solving a pair of linear equations. Algebraic method refers to a method of solving an equation involving two or more variables where one of the variables is expressed as a function of one of the other variables. There are typically two algebraic methods used in solving these types of equations: the substitution method and the elimination method.
