Step 1: Identify the hundreds place: 8 Step 2: Look at the tens place: 3 Step 3: Is 3 โฅ 5? No! Step 4: Round DOWN (keep the 8)

The 4 in the hundreds place tells us to round down.
A stadium has 48,651 people. Round this to the nearest ten thousand.
Step 1: Identify the ten thousands place: 4 Step 2: Look at the thousands place: 8 Step 3: Is 8 โฅ 5? Yes! Step 4: Round UP (4 becomes 5)
48,651 rounds to 50,000 โ

Round 9,999 to the nearest hundred. What happens?
Step 1: Identify the hundreds place: 9 (second 9) Step 2: Look at the tens place: 9 Step 3: Is 9 โฅ 5? Yes! Step 4: Round UP - but this creates a chain reaction!
9,999 โ the hundreds 9 rounds up to 10 โ This makes the thousands 9 become 10 โ This gives us 10,000!
9,999 rounds to 10,000 โ
This is a special case where rounding changes the number of digits!
