What's a Solution Set?

Systematically check a solution in a system. Given a point and a system, the presenter checks to see if the point is a solution to the system. Pupils understand what it means to be a solution to a system. The video shows both...

Always operate under the assumption that the order of operations applies. An informative video shows viewers how to use the order of operations. It goes through four examples and explains how to evaluate each expression.

Does order always matter? It sure makes things easier! Scholars learn the steps to simplifying numerical expressions by watching a short video. Of course, the order of operations must be taken into consideration.

Given a replacement set of values, plug them in to find a solution set to this inequality expression.

Given a replacement set of values, plug them in to find a solution set to this inequality expression.

Check to see if a given ordered pair is a solution to an inequality. Just plug the given values into the given inequality and do the math. If the resulting statement is true then the given ordered pair is a solution. If the statement is...

Use a table to find the solution set for an equation. Watch an instructor as she directs how to create ordered pairs using a given domain and check your answers using one of these ordered pairs. A practical video for anyone, student or...

If you plug in a value for a variable in an inequality and you get a contradiction then the inequality has no solution. Is that really possible? Yes, it is. Watch this video and see the several examples that the instructor will present...

You already know that the mode of a data set is the number that occurs most often in the set. But what if all of the numbers in the set occur the same number of times? I could tell you the answer, but I think you should watch the video.
