What is Subtraction Algorithms for 3-Digit Problems about?

The document discusses and provides examples of 5 different algorithms that can be used for subtraction: Trades-First, Counting Up, Left-to-Right, Partial-Differences, and Same-Change Rule. Each algorithm approaches the subtraction process in a slightly different way, such as trading numbers before subtracting or counting up from the number being subtracted to the number it is being subtracted from. The goal is for students to understand concepts and have multiple tools or strategies for solving subtraction
