## Engineering Performance Matrix

Algebra is a branch of mathematics that focuses on the conventions related to the use of letters and other general symbols, known as variables, to represent numbers and quantities, without fixed values, in formulae and equations. Algebra is important to Engineering Literacy as engineering professionals habitually select and use algebraic content and practices in the analysis, design, and making of solutions to engineering problems. For example, the related mathematical applications are used on a daily basis to solve formulas to determine an unknown value using a measured or known value such as the voltage in an electrical circuit using Ohm’s Law.

## Performance Goal for High School Learners

I can, when appropriate, draw upon the knowledge of algebraic content and practices, such as (a) the basic laws of algebraic equations, (b) reasoning with equations and inequalities, (c) representing equations in 2D and 3D coordinate systems, and (d) linear algebra, to solve problems in a manner that is analytical, predictive, repeatable, and practical.
