This video tutorial explores various strategies for solving basic subtraction problems. It begins with an introduction to using 10 as a benchmark to simplify calculations, followed by a method of counting backwards to find the difference. The tutorial concludes with the doubles strategy, which involves recognizing pairs of numbers that sum to a known total. These strategies aim to make subtraction easier and more intuitive for learners.
