 * __<span style="font-family: 'Comic Sans MS',cursive; font-size: 150%;">Equations __** <span style="font-family: 'Comic Sans MS',cursive; font-size: 150%;">Algebra is a division of mathematics designed to help solve certain types of problems quicker and easier. Algebra is based on the concept of unknown values called variables, unlike arithmetic which is based entirely on known number values. Many problems lend themselves to being solved with systems of linear equations. In "real life", these problems can be incredibly complex. This is one reason why linear algebra (the study of linear systems and related concepts) is its own branch of mathematics.
