Solving Multi-Step Word Problems

The video tutorial covers lesson 29 on multi-step problems involving all operations. It includes examples such as determining the number of different types of books in a library, analyzing a school sports survey, calculating lunch orders, and determining art supplies needed for a project. The tutorial emphasizes using tables, tape diagrams, and algebraic equations to solve these problems.
