In each lesson, you'll find plenty of examples so you can work along with our instructors. When you are through with this chapter, you should be able to:
- Explain probability and calculate combinations
- Understand the steps for solving word problems
- Solve multi-step word problems
- Translate words into math operations
- Solve time and money problems
Short, engaging video lessons taught by our experienced instructors make learning and review easy. Each lesson includes plenty of examples to help you master the math principles. If you want to review select topics, video tags in the Timeline let you quickly access individual segments of the video. And, when you have completed a lesson, take the self-assessment quiz to confirm you understand the new concepts. To track your progress, go to Dashboard to see what you completed.
1. What is Probability in Math? - Definition & Overview
Remember throwing a quarter and calling out heads or tails? Learn what this has to do with probability. Also learn how you can use your newly-learned skills from this lesson to help you decide whether you should play heads or tails at all!
2. How to Calculate the Probability of Combinations
To calculate the probability of a combination, you will need to consider the number of favorable outcomes over the number of total outcomes. Combinations are used to calculate events where order does not matter. In this lesson, we will explore the connection between these two essential topics.
3. 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.
4. 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.
5. How to Solve Problems with Time
It's amazing how much time can be saved when people work together. In this lesson, we'll practice figuring out just how much time we're talking about as we solve problems involving time.
6. How to Solve Problems with Money
Money matters, and knowing how much things cost will be useful no matter where you go. In this lesson, we'll learn the steps for solving word problems involving money.
7. Translating Words Into Math Symbols
Math is its own language, which can make solving problems difficult. This lesson will help you translate words into math symbols, so you can easily solve word problems.
