[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 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.

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 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)

[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 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.

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 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.
