Working Backward in Problem Solving

The video tutorial by Houston Math Prep introduces the problem-solving strategy of working backwards. It uses Julio's budget changes over the past year as an example. The video explains how to calculate Julio's budget from a year ago by reversing the changes made to his current budget. The strategy involves understanding the problem, devising a plan, and applying the working backwards method to find the solution. The tutorial concludes with a review of the strategy's effectiveness.
