Math is not just for scientists and people walking around with pocket protectors (Do they still use those?). Everyone can benefit, both in their everyday life and in business with an understanding of how to do math quickly and easily in his head. At the grocery store, in a restaurant, when dealing with suppliers and payroll…math is a part of our every day personal and business life.
Don’t just watch the videos, though. You must practice and review until it is second nature to you. To help in that, I will be creating a workbook with supplementary problems. It will be posted here. Until then, though, just try to use these methods in your everyday life and you will find that math is not as difficult as you may have thought.
