Exploring Decimals and Their Operations

The video tutorial covers the process of adding decimals with different decimal places. It begins with a review of the steps involved, such as aligning decimal points and adding trailing zeros. The teacher then guides students through solving even-numbered problems from their workbook, demonstrating how to add decimals and regroup when necessary. Each problem is solved step-by-step, emphasizing the importance of place value and correct decimal placement in the final sum.

What is the first step when adding decimals with different decimal places?
