Algebra 2 Grade Level

Welcome to the Algebra 2 Grade Level page.

Here we look at some more involved areas of the subject than those listed in the Basic Algebra Help section.
With an aim at looking to solve more complex problems, and dealing with more involved equations.

Derived from the word of Arabic origin Al – Jabr, generally meaning “reunion of broken parts”. Algebra certainly does cover a very broad range of concepts, many of which can be applied to real world problems and situations.

Many common algorithms used today are based and rely on algebraic concepts. Underlining the importance, and relevance of the subject. Math used in complex numbers and matrices for example has a wide range of applications in real world problems.

Once one gets their head around the basics and develops a good understanding of the key concepts, Algebra can really be very fascinating.
