The video tutorial covers solving two-step word problems using multiplication and addition. It begins with an introduction to the concepts, followed by solving a problem about Mrs. Chessman buying items for her students. The solution involves calculating the total number of items using both repeated addition and multiplication. The second problem involves Mary and Terry's shells, where Terry has three times as many shells as Mary. The solution demonstrates how to calculate the total number of shells by using multiplication and addition. The tutorial emphasizes understanding the problem, identifying key information, and applying mathematical operations to find the solution.
