Place value of a number
While writing a number, position of each digit is important. Each digit has its own place value. Place value starts from Units or Ones place. The place values are:
In the example above 5 is in units place, 4 is in tens place. That means number 45 contains 4 tens and 5 ones.
In the example above the units and tens place has 0 and and hundreds place has 1. That means, number 100 has 1 hundred, 0 tens and 0 ones.
As we move left, value of each digit increases by 10. This means, each position is 10 times bigger (more) than the previous digit. Similarly, as we move right, value of each digit decreases by 10. This means, each position is 10 times smaller (lesser). This system of numbers is called Decimal System.
