Adding Multi-Digit Whole Numbers (Example)

The video tutorial demonstrates how to add three numbers with different digit lengths by aligning them according to their length. The process involves arranging the numbers so that the longest is on top and the shortest is at the bottom. The tutorial then guides through the addition process column by column, starting from the rightmost digit. The final result of the addition is presented as 984,368.

Why is it important to arrange numbers by length before adding them?

• To avoid using a calculator

• To make the numbers look neat

• To ensure the numbers are aligned correctly

• To make the addition process faster
