The Essentials of Mathematics course at ICA is a semester-length review of the fundamentals taught in Pre-Algebra, Algebra I, and Geometry courses and is useful at the high school level for basic skill remediation and/or practice necessary to prepare for a state exam. The course highlights basic mathematical skills through multiple review, practice, and sample exam questions. There is one final exam, and there is a unit test in each of the six units.
Topics of study include working with percents, negative whole-number exponents, probabilities, and polynomials, as well as converting between units of measurements, graphing high power functions, solving absolute value inequalities, and more.
