This video tutorial teaches how to add large multi-digit numbers using the standard addition algorithm. It covers aligning numbers correctly, adding common place values, and regrouping. The tutorial provides a step-by-step guide to solve the example problem of adding 254,876 and 23,087, resulting in 277,963. The lesson emphasizes the importance of correct alignment and visualization using a place value chart.

What is the main focus of this lesson?

What happens when you add six ones and seven ones?

• You multiply the numbers

• You subtract the smaller number

• You regroup to form a group of ten

• You get thirteen ones

What is the purpose of regrouping in addition?

• To make the numbers smaller

• To simplify subtraction

• To carry over excess to the next place value

• To divide the numbers
