Regrouping and Decomposing in Subtraction with Zeros in the 10s or Ones Places

This video tutorial teaches how to regroup when subtracting by decomposing hundreds or tens. It uses base 10 blocks to illustrate the process of breaking down numbers to facilitate subtraction, especially when there are no tens or ones available. The tutorial provides examples of subtracting numbers like 700 - 342 and 571 - 328, demonstrating how to decompose hundreds into tens and tens into ones to complete the subtraction process.
