Exploring the Basics of Distributing Expressions

This video tutorial covers the basics of distributing expressions, starting with the order of operations. It introduces a visual method using blocks to represent numbers and expressions, making it easier to understand and solve problems. The tutorial then extends this method to expressions involving variables, providing a foundation for more complex mathematical concepts. Finally, students are given instructions for independent practice to reinforce their learning.
