Translating Words into Mathematical Expressions

In this video, Tiffany explains how to translate verbal phrases into mathematical expressions. She covers key concepts such as identifying variables, understanding operations like addition, subtraction, multiplication, and division, and the importance of order in expressions. Through four examples, she demonstrates how to convert phrases like 'a number increased by 12' and 'four less than a number' into math expressions, emphasizing the need to switch terms when using 'than'. The video concludes with a reminder that variables can be any symbol, not just letters.

What should you remember to do when you see the word 'than' in a math problem?

• Add the terms

• Multiply the terms
