Worked Example
Compare the value of the digit 7 in 74,200 and the digit 7 in 7,420:
1
Identify place value position in 74,200
7 is in the ten-thousands place = 70,000
The 7 represents 7 * 10,000 = 70,000.
2
Identify place value position in 7,420
7 is in the thousands place = 7,000
The 7 represents 7 * 1,000 = 7,000.
3
Divide the two values
70,000 / 7,000 = 10
The 7 in 74,200 is exactly 10 times greater than the 7 in 7,420.
✓Verification Check
Multiply 7,000 by 10 to confirm: 7,000 * 10 = 70,000.
7,000 * 10 = 70,000
•
70,000 = 70,000 (Verified)
⚠️ Common Pitfalls & Misconceptions
Thinking a digit always has the same value regardless of column
✗ Believing the 5 in 520 has the same value as the 5 in 52✓ Value = Digit * Column Value (5 in hundreds = 500, 5 in tens = 50)
A digit’s magnitude depends strictly on its place value column.
