Adding Multi Digit Whole Numbers with a Carry

The video tutorial explains how to add two multi-digit numbers, 12,417 and 9,135, using the column method. It demonstrates aligning numbers by place value, starting from the rightmost digit, and adding each column while carrying over extra digits to the next column. The process is detailed for ones, tens, hundreds, thousands, and ten thousands places, resulting in a final sum of 21,552. The lesson emphasizes the concept of carrying over in addition.
