Prefixes and Root Words
This lesson teaches what prefixes are and how they function in word formation. Students will learn to identify basic root words and use prefixes to create antonyms. The concept of morphemes as the smallest units of sound will also be explained.

Polynomials and Their Properties
This lesson covers the definition of polynomials and their degrees. It explains how to divide a polynomial by another polynomial of lesser degree and introduces the remainder theorem. Additionally, it discusses how to find factors of polynomials and solve cubic equations using their roots.
- 00:49 “Now, let's define what polinomia is. An expression of the form a, n, x, roots of power n plus a, n minus 1, x, roots of power n minus 1 plus. Obviously, when you have a, x squared, a, 2, x squared plus a, 1, x plus a, kn...”
- 02:25 “and the IS degree of polinomia is 2, because that is the highest power of unknown, which is 2. So, example are, when we have p of x, so we always denotes our polinomia to be p of x equals this. So, we only denotes our po...”

Chemical Symbols and Formulae
The lesson covers the symbols of the first 20 elements and how to write chemical formulae and equations. It explains the differences between elements, compounds, and mixtures, as well as the concept of radicals and valency. The laws of conservation of mass and constant composition are also discussed
- 07:31 “with a radical, I put brackets. So the formula is C-A-O-H2 for potassium. Hydrozyde. I believe you understand that example. The next is, how do I name? How do I name compounds? How do I name formulas? When they stand tha...”
