MATH: We use calculators, financial and graphic scientific - we teach the use of all of the functions these can perform, in three weeks, with a refresher course each six months. The scientific calculators include algebra, calculus, statistics, geometry, trigonometry, probability, programming, and others. The business financial calculators include present values, ROI, risk calculations and mitigation, and a lot of stuff our students and you have not heard of. Public ed, in elementary and high school, takes two years for each of algebra, two years for calculus, one year for a light form of statistics, one year for geometry, one year for trigonometry, ZERO probability, ZERO programming. Even then, the teaching is couched in a manual development of the skill - a difficult history course that is totally unnecessary and time-wasting. Isaac Newton would be ashamed of us. Public Ed has changed calculus into a history of math course. Our math courses teach the use of the skill, using calculators, Apprentice-Ed does NOT teach the wasteful history of the course, using manual calculations. As a result, we can teach the above subjects in less than 100 hours per year. But we teach much more in school from age 6 to age 25 - risk theory, risk identification, and risk mitigation'; product pricing and price reaction to outside stimulus; market penetration using probability models (all on our calculators) - necessary for our business program, and much more.
