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.
