๐ Understanding Place Value and Face Value
In mathematics, especially when dealing with numbers, it's crucial to understand the difference between place value and face value. These concepts help us understand the significance of each digit in a number.
๐ Definition of Place Value
The place value of a digit refers to the value it holds based on its position in the number. For example, in the number 345, the digit 3 is in the hundreds place, so its place value is 300.
๐ญ Definition of Face Value
The face value of a digit is simply the digit itself, regardless of its position in the number. Using the same example, 345, the face value of the digit 3 is just 3.

| Feature |
Place Value |
Face Value |
| Definition |
The value of a digit based on its position in the number. |
The actual value of the digit itself. |
| Dependence on Position |
Depends on where the digit is located (ones, tens, hundreds, etc.). |
Does not depend on the digit's position. |
| Example (in 456) |
Place value of 4 is 400. |
Face value of 4 is 4. |
| Use |
Used to determine the overall value of a number. |
Used to identify the digit itself. |
๐ Key Takeaways
- ๐ข The face value of a digit is the digit itself.
- ๐ The place value depends on the position of the digit in the number.
- ๐ก Understanding both helps in solving math problems related to number values.
- โ For example, in the number 62, the face value of 6 is 6, but its place value is 60.
- โ Similarly, in the number 987, the face value of 8 is 8, but its place value is 80.
