Mathematical Expressions and Simplification

Mr. Fish guides students through a math simplification process, focusing on factorization and canceling terms. He explains how to factor numbers and write expressions, then demonstrates canceling terms to simplify the expression. The video concludes with a final result and additional explanations on the process.

What is the first step in simplifying a mathematical expression?

• Divide the numbers

• Add all the numbers

• Factor the numbers

• Multiply the numbers
