Algebra is a branch of mathematics in which letters (known as variables) and numbers are combined to address abstract entities using basic rules of arithmetic. We use algebra to interact with the world around us by solving problems that deal with unknown variables, various relationships, graphed equations, and more. Major algebraic concepts include the following:
Symbols and Expressions – identifying relevant information in order to solve the problem correctly
Linear and Quadratic Equations – Graphing and Solving Equations
Functions – working with various equations including polynomials, inputs, and outputs
Solving for unknown variables – one of the more basic skills used to identify unknown entities or missing information
Applying algebraic knowledge to functional word problems – applying algebraic knowledge to real world situations
When we learn basic algebra, we open the door for more challenging mathematical concepts. The more comfortable we are with these skills, the stronger your mathematical foundation will be in the future.
