Expanded Form Addition Concepts

The video tutorial teaches how to add three-digit numbers using expanded form. It begins with an introduction to the concept and explains how to break down numbers into hundreds, tens, and ones. The tutorial provides examples, including adding 384 and 415, 731 and 256, and 324 and 131, demonstrating the step-by-step process of using expanded form to simplify addition. By the end, viewers will understand how to apply this method to add any three-digit numbers efficiently.

What is the expanded form of the number 222?

• 200 + 20 + 2

• 2 + 2 + 2

• 22 + 2

• 220 + 2

Why is it incorrect to say the expanded form of 222 is 2 + 2 + 2?

• Because it doesn't include zero

• Because it is not a three-digit number

• Because it uses subtraction

• Because it adds the digits, not their values
