Understanding the Dot Method

The video tutorial introduces a simple method for adding numbers using dots. It demonstrates how to visualize numbers with dots and add them together, both horizontally and vertically. Examples include adding 2 + 3 and 2 + 2 using this method. The tutorial concludes by suggesting the method can be extended to numbers up to nine.
