Place Value

What is Place Value in maths?

In Math, place value is concerned with the actual worth of a digit in relation to its position within a number. Every digit’s value changes based on its position in the number. For example, in the number 345, the 3 represents three hundred and not just three since it is in the hundreds place. Place value assists us in keeping track of our counting system.

Place Value and Expanded Form

Expanded form shows the value of each digit in a number based on its place.

Example

67,891,234 = 60,000,000 + 7,000,000 + 800,000 + 90,000 + 1,000 + 200 + 30 + 4

 

Face Value vs Place Value

The above table shows the difference between face value and place value

 

Place Value for Decimal Numbers

Example: In 345.678 - 3 = Hundreds (300) - 4 = Tens (40) - 5 = Ones (5) - 6 = Tenths (0.6) - 7 = Hundredths (0.07) - 8 = Thousandths (0.008)

 

Common Mistakes and Tips

• Don’t confuse place value and face value.

• Always align digits by place value in arithmetic.

• Zeros are crucial as placeholders.

 

Applications of Place Value in Real Life

• Currency calculations

• Measurements and conversions

• Data interpretation

• Computer science (binary values)
