This lesson explains the simple rule based on the difference between the sums of digits in odd and even positions. Through clear examples, it shows how large numbers can be tested mentally without doing long division. The video also explores an interesting palindrome example that makes the idea even more engaging. A fun and clever number trick that helps students work faster and think smarter with numbers.
