What is Place Value?
The place value of a digit tells us which position it holds in a number. The rightmost digit represents the highest place value, while the leftmost digit represents the lowest place value.
How to Read Place Values?
Start with the rightmost digit.
Move left to right, counting the place values in order.
The digit in the rightmost position represents the highest place value.
The digit in the next position represents the second highest place value.
This process continues until you reach the leftmost digit, which represents the lowest place value.
Examples:
12.34
Rightmost digit: 1 (Hundreds place)
Second rightmost digit: 2 (Tens place)
Third rightmost digit: 3 (Units place)
Leftmost digit: 4 (Ones place)
Therefore, 12.34 = 1234.

Place value allows us to compare and order decimals accurately.
It helps us solve problems involving decimals, such as adding, subtracting, and multiplying them.
Understanding place value is crucial for mastering other concepts in mathematics, such as fractions and percentages.
Additional Notes:
The place value system is consistent for all numbers, regardless of the base of the number system used.
The place value of a decimal point is always indicated by a decimal marker.
