This video tutorial explores various strategies for solving basic subtraction problems. It begins with an introduction to using the number 10 as a reference point to simplify calculations. The tutorial then demonstrates the counting backwards method, followed by the doubles strategy, which involves recognizing pairs of numbers that add up to a specific total. Each strategy is explained with examples to help learners understand and apply them effectively.
