| |  | Algebra: Solving Linear Equations - Part 2: Applications
19:38
[NOTE: This video is only the first 20 minutes of the full lesson, please visit my website to purchase complete version] This lesson consists of providing more...you with a Self-Tutorial on how to solve typical linear word problems (story problems or applied problems). The tutor shows you how to solve for a specific variable in formulas. He also discusses how to covert a repeating decimal into a fraction (which was skipped in Basic Math: Lesson 6 -"Fractions") and will teach you how to convert units of measurement.
Examples of word problems done include:
Finding a number based on certain criteria.
Word problems involving some geometry (triangle, rectangle, circle).
Age problems.
Mixture problems.
Money problems (story of my life!).
Rate-Time-Distance problems.
Percent Equations/problems.
Ratio and Proportion (concepts and solving problems, including similar triangles).
Problems dealing with Unit Price. less

|  | Algebra: Solving Linear Equations – Part 1: The Basics
18:21
[NOTE: This video is only the first 18 minutes of the full lesson, please visit my web site to purchase complete version] Lesson consists of providing more...you with a Self-Tutorial on how to solve linear equations. I discuss what is an Equation, Solution, Solution Set, Equivalent Equations, Identity, Contradictions, Conditional Equations, Linear Equations, the Standard Form of a Linear Equation. I show you how to actually SOLVE linear equations going step-by-step. I don't skip steps. I review some of the properties of Equality here too. I remind you to check the work done and how to solve linear equations using a calculator. At the end, you will know how to easily solve equations that look like:
2[y - (4y - 1)] = 5 - 9y
No word problems are done here. This is shown in DETAIL in Part 2 of the Lesson. less

03:37
This video is to help students in math and science classes learn the Greek alphabet. The pronunciation is the English way of saying the letters in an more...American accent. It is NOT meant for those actually trying to learn Greek as a foreign language. less

|  | Algebra: Formulas From Geometry
23:07
This lesson consists of providing you with a basic review of the formulas from geometry you will most likely encounter in algebra (and other math classes more...like trigonometry and calculus). This is NOT a detailed, formal lesson.
Formulas and concepts covered include:
Angles (complementary & supplementary)
Triangles (perimeter and area)
Isosceles triangle
Equilateral triangle
Right triangle
The Pythagorean Theorem
Similar triangles
Perimeter and area formulas for Quadrilaterals (square, rectangle, parallelogram, trapezoid). Some diagonal formulas too, where applicable.
Circles (radius, diameter, circumference, area)
Cube (diagonal of face, diagonal of cube, surface area and volume)
Rectangular box [or Rectangular Parallelepiped] (diagonal of box, surface area and volume)
Prisms (Volume)
Pyramids (Volume)
Cone (slant height, lateral surface area, total surface area, volume)
Cylinder (lateral surface area, total surface area, volume)
Sphere (surface area and volume) less

11:24
[NOTE: This video is only the first 11 minutes of the full lesson, please visit my web site to purchase complete version] This lesson consists of providing more...you with a Self-Tutorial on what is algebra, what are variables, constants, coefficients, terms, and expressions. I explain the use of proper notation, how to combine like terms, find the negation of an algebraic expression, how to evaluate an expression (by hand and by using your calculator), and finally, there is a VERY detailed section on how to translate English phrases into algebraic expressions. less

|  | Basic Math: Lesson 7 - Units of Measurement
31:43
This lesson consists of providing you with a Self-Tutorial of the basic units used in measurement. These are the ones I discuss:
Units of Time, Units more...of Length (Metric and U.S.), Units of Area (Metric and U.S.), Units of Volume (Metric and U.S.), Units of Mass (Metric and U.S.), Units of Liquid Capacity (Metric and U.S.), Units of Dry Capacity (Metric and U.S.), and other miscellaneous Units. Conversion Formulas and Abbreviations are also listed.
This is a "must have" Lesson for those moving on to solving Word Problems in Algebra and other higher math. less
