Educational Resource — Mathematical Secondary Education — UD.6-Algebra

Since the Babylonian epoch and ancient Egypt it has been recorded the resolution of algebraic problems, knowledge that joined Greek, Chinese and Indian mathematics and over the centuries has formed what is now known as the ÁLGEBRA, one of the fundamental branches of mathematics.
Two didactic proposals are presented, one with the contents on algebraic language and the resolution of equations necessary to start algebra in Secondary, and another with informative interest, in which algebraic formulas are sought that serve everything.
