Concept
Comparing 3-digit numbers requires you to be a detective, reading from Left to Right.
π― The "Left to Right" Check: Let's compare 438 and 452. 1. Check the Hundreds (Left): Both have a 4. It's a tie! Go to the next digit. 2. Check the Tens (Middle): The first number has a 3. The second number has a 5. 3. Winner! 5 is bigger than 3. We don't even need to look at the Ones column! 4. The Sign: 438 < 452. (The alligator mouth opens towards the 452).
If the hundreds are different (like 512 and 388), you stop immediately. 500 is bigger than 300!
