Mathematical Operations and Word Problems

The video tutorial covers graphing number patterns using input-output tables. It explains how to multiply and add values to inputs, plot them on graphs, and interpret the results. The tutorial also includes practical examples like architectural drawing scales, calculating bulbs in packages, and analyzing fundraising and spending patterns.
