Solving Equations by Adding or Subtracting. Mathematics in Action Prealgebra Problem SolvingUse the distributive property to simplify algebraic expressions. In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols it is a unifying thread of almost. 'reunion of broken parts, bonesetting') is one of the broad areas of mathematics, together with number theory, geometry and analysis. Algebra (from Arabic: , romanized: al-jabr, lit.
