Where many multiplying binomial lessons introduce the tool of FOIL and move on, this video presentation really delves into the how's and why's of the distributive property. Careful treatment of distribution and explicitly written out...

Here's help in making the giant leap from finding real to finding complex roots. Careful and thorough in explanation, the theory of polynomial algebra is briefly touched upon before the examples really dive into the application...

Fantastic! This clip is wonderful for homeschoolers, parents who want to help their young mathematicians at home, or a teacher just starting out. Watch as Shey uses a manipulative to solve basic addition problems, and learn how easy it...

Sometimes a little manipulation goes a long way. The sixth of 18 videos in Unit 1 - Limits and Continuity shows viewers how to use algebraic manipulation to determine limits. They first use substitution and factoring, then apply special...

Change places by pivoting the figure. The section of a geometry playlist introduces rotations by making the connection to rotational symmetry. The presentation provides formulas to use with the coordinates when rotating a figure around...

Explore the meaning of equivalent fractions. A video instructor shows the process of creating equivalent fractions both visually and mathematically. After explaining how to create equivalent fractions from the most simple form, she...

The instructor uses the temperature formula to illustrate how the variables can be manipulated to solve a problem.

The instructor uses the temperature formula to illustrate how the variables can be manipulated to solve a problem.

Decaying car sales ... when should the advertising resume? The last video in a series of 31 works a problem involving exponential decay. The problem presents the scenario of declining car sales in which the rate is not given directly to...

Nothing but net! Pupils learn to use nets to create a two-dimensional representation of a three-dimensional figure. The instructor explains each section of a net of a cube and then of a rectangular prism. 

Sal begins this video by "massaging the equations slightly to prepare them for elimination." The equations won't be the only relaxed part of this lesson, which introduces the concept of multiplication to systems of equations. Viewers...

You're trapped in a dark castle with a pile of gold coins that a wizard will only allow you to leave with if you can solve his riddle. Math learners solve the riddle of the dark coin with the help of an engaging instructional video.

Your geometry learners will appreciate this net for a square pyramid. Copy, cut, and manipulate to explore the surface area or volume of a square pyramid.

Viewers discover how to apply derivatives to determine dimensions that maximize area with a video that presents a problem that asks for the maximum area of a rectangle inscribed in a circle with radius (r). The instructor demonstrates...

Video can be a powerful tool in the learning process. This one makes use of digital tools to help explain the concept of conditional probability applied to a lottery problem. 

Investigate the process of solving linear equations with variables on both sides with a video that demonstrates a simple example that requires the variables to be manipulated to one side of the equation. The second example is more...

Take an example out of more advanced math. Pupils observe how basic algebraic concepts help solve expressions from higher level math courses. The video from a Mathispower4u Algebra 1 series shows the evaluation and simplification of the...

Use slope to find the location of horizontal and vertical tangent lines. Using the derivative of a radical function, the presenter finds the points where the derivative is zero or undefined on a given interval. The 26th in a series of 31...

A short video introduces the triangle that illustrates how to find any value given the other two in the density formula. Class members use the triangle to work several problems to find the mass, volume, or density of an object.

Explaining the hows and whys of exponent laws in an approachable and non-intimidating manner is no small task. But here, it is accomplished with humor and real-life examples. Set up with scenarios from biology, the role of exponents and...

Connect integrals with differentiation. The beginning of the video introduces the definition of an accumulation function. Scholars learn about the relationship between integrals and derivatives. Using what is commonly known as Part Two...

Sal dissects basic algebraic equations of the form Ax=B. He encourages viewers to fully understand the equations before learning how to manipulate them. Furthermore, he teaches students how to solve the equations systematically. The...

Sal starts to solve a trigonometric word problem of a wayward ship captain who veers off course and once aware of his predicament, needs to know how far he is from his destination. Instead of using the Law of Cosines in his solution, Sal...

This video proves the helpful change of base formula for logarithms. The proof steps may need to be more intuitive to most logarithm learners, but the algebraic manipulation shown using logs is interesting.
