We also graph algebraic equations, on a coordinate plane, which allows the equations to be represented geometrically as curves. This connection between algebra and geometry allows for a deeper understanding of both subjects - more powerful methods for solving algebraic problems by geometric methods, and more powerful methods for solving geometric problems by algebraic methods. While graphing calculator can enhance our ability and efficiency in this regard, these are the standards that students must be able to meet without their use. I High school graduates will use symbols to represent unknown quantities. They will evaluate algebraic expressions and formulas, in both concrete and abstract settings, and correctly interpret the results.
Formulas are increasingly pervasive in the workplace and in personal finances.
Correctly evaluating them is the most basic skill in using them. Each year the employee pays an amount P into the savings account. Standard II High school graduates will analyze suitable problems that arise in everyday contexts and represent them as equations or inequalities to be solved. Before algebraic skills can be used to solve a problem, the problem must typically be correctly stated as an algebraic equation to be solved. The person who can make the abstraction to find the equation that describes some situation has a distinct advantage in solving problems.
