### About This Chapter

## CEOE Middle Level/Intermediate Math: Mathematical Modeling - Chapter Summary

Our instructors developed these entertaining video lessons to get you ready for your upcoming CEOE Middle Level / Intermediate Math testing session. The lessons will aid in answering exam questions dealing with:

- The steps to take in solving word problems
- Solving word problems by using images or restating the words used
- Increasing understanding by personalizing the word problem
- How to change words into algebraic expressions
- The use of mathematical models in problem solving
- Utilization of the greater than and less than symbols in math

These short and engaging lessons are each followed by a multiple-choice quiz to check your understanding and retention of the material. There is a feature that allows you to ask a question of an expert while on course. It's located in the Dashboard area.

### 1. Solving Word Problems: Steps & Examples

Watch this video lesson to learn how you can solve word problems by following this 3-step process. Learn how to visualize your problem so you fully understand it. Then learn how to write and solve your equations.

### 2. Solving Word Problems with Multiple Steps

Not all word problems are so straightforward that they only require you to do one operation and you're done. Some are more complicated, requiring several steps. Watch this video lesson to learn how to solve these kinds of problems.

### 3. Restating Word Problems Using Words or Images

Watch this video lesson to learn how you can use sketches and notes to help you visualize a problem. Watch how easy it becomes to solve your problem once you have visualized it.

### 4. Personalizing a Word Problem to Increase Understanding

When it comes to word problems, being able to personalize a word problem with more familiar situations will help you a lot in your problem solving. Watch this video lesson to learn how you can restate the word problem in terms you understand.

### 5. Translating Words to Algebraic Expressions

When it comes to word problems, the easiest way to solve them is to look for keywords and change them into math symbols. Watch this video lesson to find out what keywords you should look for and what math symbols they represent.

### 6. Using Mathematical Models to Solve Problems

Mathematical modeling simply refers to the creation of mathematical formulas to represent a real world problem in mathematical terms. This lesson reviews the creation and pitfalls of mathematical models.

### 7. Greater Than Symbol in Math: Examples & Problems

This lesson explains what the 'greater than' symbol is and how to use it to compare numbers in mathematics. You'll learn when to use the 'greater than' symbol how to tell the difference between the 'greater than' and 'less than' symbols, then you'll be quizzed about what you've learned.

### 8. Less Than Symbol in Math: Problems & Applications

The less-than sign is a sign of inequality. It is represented by the < symbol. This lesson will describe the properties of less-than inequalities, show some example problems and provide a quiz at the end.
