In math, every digit in a number has a place value.
<h3>What is place value?</h3>
Place value can be defined as the value represented by a digit in a number on the basis of its position in the number.
For example, the place value of 7 in 3,743 is 7 hundreds or 700. However, the place value of 7 in 7,432 is 7 thousands or 7,000. Here, we can see that even though the digits are same in both the numbers, it’s place value changes with the change in it’s position.
The place value of a digit increases by ten times as we move left on the place value chart and decreases by ten times as we move right.
