Understanding Basic Addition in Standard Form

The video tutorial introduces the concept of Bentuk Lazim, a method for solving addition problems by organizing numbers according to their place values. The teacher provides several examples, such as adding 30 + 4, 21 + 5, and 70 + 15, demonstrating the step-by-step process of using Bentuk Lazim. The tutorial also includes exercises where students fill in missing numbers in equations. The session concludes with a summary and homework assignment instructions.
