The video tutorial explores various mental strategies for adding numbers. It begins with an introduction to the concept of using mental strategies to simplify addition problems. The tutorial covers four main strategies: counting on, using the number 10, adjusting numbers, and using doubles. Each strategy is explained with examples to demonstrate how they can make addition easier. The video aims to equip learners with techniques to solve basic addition problems more efficiently.
