Basic Mathematics (Subtracting decimal numbers from whole numbers)

This is the introduction to my series on Basic Mathematics. Basic Mathematics will get you up to speed so you're ready for Calculus and thus Physics. It will teach you logic, theorems and proofs at the same time reviewing everything you should've learned in algebra, geometry, and trigonometry. If you're a beginner at more advanced mathematics, or just want to review, this is the series for you.
