Adding Multi-Digit Numbers Concepts

The video tutorial explains how to add multi-digit numbers by aligning them according to their place values. It introduces the concept of carrying over when the sum of digits exceeds nine. Two examples are provided: adding 536 and 456, and adding 956 and 319. The tutorial concludes with a brief mention of the next topic, multi-digit subtraction.
