The video tutorial explains the concept of like and unlike terms using relatable examples such as cows and liters of milk. It demonstrates how to add like terms and why dissimilar terms cannot be added. The tutorial also covers grouping numbers, simplifying expressions, and using the column method for addition. Finally, it explains how to subtract expressions using both column and line methods.
