How Do You Write a Relation from a Word Problem?

Help young mathematicians crack the code of word problems with this three-lesson series on problem solving. Walking students step-by-step through the process of identifying key information, creating algebraic equations, and finally...

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...

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...

For most people, solving word problems takes a lot of work. But Sal makes it look simple! Follow along as he unpacks this complicated word problem. He even demonstrates how to answer. Excellent!

Sal takes your class’ newfound (or growing) knowledge of graphs of lines to the next level. He presents a few word problems in which mathematicians need to understand how to use linear function graphs.

Concepts from the last few videos, particularly exponential growth and decay functions, are covered in this video about word problems. Viewers can apply their new (or growing) algebraic knowledge to solve the word problems along with Sal.

Three word problems involving measurements, percentages, and expenditures are the focus of this video. Sal shows how to translate word problems into solvable equations.

Your algebra learners will pick up some solid algebra problem solving skills and a plan of approach for some typical types of word problems in this scripted learning exercise that shows how to set up and organize each type of...

There are rabbits, rabbits, rabbits everywhere. Not this group of rabbits. Use a table to find some x and y values to create a graph to solve this word problem. It's a rather peculiar word problem in that it is trying to find when a...

Are you befuddled after reading this word problem? Not only is it a word problem but there are two variables, and not only does it have two variables, but it is an inequality. Don't pull your hair out! Take a deep breath and watch this...
