At about the 4:34 mark, the teacher says let's say I have $30, and you have 1 less dollar than me, then you have $19; He should have said either I have $20 OR you have $29.
In this lesson, we learn how to solve one-variable word problems using verbal expressions. The first step is to read the problem and determine what is being asked, followed by defining a variable to represent the unknown value. We then break down the problem into smaller parts and use math operations to solve for the variable. Finally, we restate the answer in the context of the original problem. With these steps, we can approach word problems with confidence and understanding.
Solving a word problem with verbal expressions
I show how to solve math problems online during live instruction in class. This is my way of providing free tutoring for the students in my class and for students anywhere in the world. Every video is a short clip that shows exactly how to solve math problems step by step. The problems are done in real time and in front of a regular classroom. These videos are intended to help you learn how to solve math problems, review how to solve a math problems, study for a test, or finish your homework. I post all of my videos on YouTube, but if you are looking for other ways to interact with me and my videos you can follow me on the following pages through My Blog, Twitter, or Facebook.
