How Are Expressions Used in The Real World?
A girl wants to read 2 books in her summer vacation, and she doesn't have those books yet. Therefore, she is not sure how many pages will be there in each of those books. She doesn't want to wait until the last sec to read the books, so she planned on reading the same number of pages for the entire summer vacation.
If her summer vacation is 72 days long, how can she write an expression for representing the number of pages she would need to read each day.
Here is how you can learn how the expression is useful in real-life situations.
A variable expression is a mathematical phrase that contains different variables, operations, and numbers.
Here are some of the examples of an expression:
- 3x + y - 10r − x - B3 + 2 - Mx – 4. An expression can be used for defining a real-life situation where there are one or more quantities that are the unknown value or can have a change in value.
