Finding the Unknown Factor Using the Multiplication Table

This video tutorial explains how to use the multiplication table to find unknown factors in equations. It demonstrates solving two equations: one where the unknown is a factor in the row and another where the unknown is a factor in the column. The tutorial concludes by summarizing the method of using the multiplication table to identify unknown factors.

What is the primary purpose of a multiplication table?

• To find unknown products and factors

• To add numbers quickly

• To divide numbers easily

• To subtract numbers efficiently
