SAT Prep: Test 7 Section 5 Part 2

A brief presentation with laser-like focus, this video talks young mathematicians through the mechanics of simplifying algebraic fractions by factoring trinomials. While the factoring itself is assumed to be a mastered skill, the...

Take your class through the mechanics of simplifying algebraic fractions by factoring trinomials. Though the steps for factoring are assumed known, the process of identifying and canceling common factors are detailed with...

In this part 2 video, Sal finishes the trigonometric word problem of the wayward ship captain. He wisely continues the algebra work on the problem before finally turning to his calculator for the very last calculation.

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

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...

The sum of three consecutive odd integers is 231. What is the largest integer? See how to unpack this word problem, set up an equation, and solve for the variable.

Sal illustrates more involved equations in this last video in a series. It follows "Simple Equations" and "Equations 2". He continues using color-coded markings to help increase students' understanding of a more complicated equation:...

In this video, Sal solves a word problem sent in by a listener with two cyclists riding towards each other over a given time. It is an interesting problem regarding ratios and the relationship between distance, rate, and time. He shows...

The next time you are at an amusement park you may want to consider all the interesting math problems you could do! Using trigonometric ratios, some logic and algebra, Sal solves a problem in this video of finding a person's height off...
