Solve this real world word problem in just one written step. The original inequality is a division problem, so to solve it, use the multiplication property of inequality. Was the problem solved by multiplying a negative number? Yes! So...

Don't skip this word problem! Take one piece at a time in writing out this inequality. Once you have an expression that represents the words in this inequality, the rest will seem easy. So watch this video to get a better understanding...

Age becomes a problem. Learners see how to set up and solve age word problems. The video goes through two examples of word problems relating the ages of people. The first example uses the relationship between the ages of two people and...

Broken lights at the skating rink? Are there enough not broken to be able to see well enough to skate? Set up this real-world word problem and find the total number of lights in the skating rink. Two given values and one variable. Solve...

Not all videos are made equal. Viewers of a short YouTube video see how to solve one-step inequalities. It also covers how to graph the solution set to an inequality before showing how to apply inequalities to a real-world situation.

Here's a real-world word problem. It involves walking for a certain amount of time. There are some given values to use. So take the given values, set up the ratio and then convert that to a unit rate value. Now use this unit rate to get...

Could anyone really eat 15 feet of a sub sandwich in one day? That's how much this math problem says he ate. He actually started out with a bigger sub sandwich. How big was it to start? The instructor uses a table to illustrate how you...

A word problem with one variable and two given numbers. This word problem seems doable from the start. Wait, it's an inequality. Don't worry about that piece, just get the expression written and do the math. Watch this video and see how...

Don't be afraid of this word problem because it has an inequality. There is only one variable and this inequality can be solved in one step. It's pretty straightforward.

This real-world word problem seems pretty complicated, but it's really not. It only takes four steps once you have an original expression to solve this problem. There are some negative numbers involved in this inequality. So don't forget...

After reading this inequality word problem, young learners might just skip over it and not even make the attempt to solve it. It seems rather complicated. So watch this video as the teacher explains all that needs to be done to solve...

Here's the solution to your equation-solving needs. An informative YouTube video discusses how to determine whether a value is a solution to a one-step equation. It then goes on to solve these types of equations using addition or...

You can't solve the inequalities of the world, but you can solve these problems. An insightful video shows pupils how to solve one-step inequalities involving addition or subtraction. It covers two mathematical examples and one...

The instructor first identifies what formula to use to solve this word problem. Then she explains what each of the variables stands for and helps match up their given values in this word problem. There are many components to solving this...

One variable and two given values. Easy as pie, right? No, not for everyone. Word problems are often skipped over. This one is good for practicing. Identify the variable and figure out where the two given values go. Now solve.
