Place value are very useful to compare given numbers. Place value gives ideas on how big the number is and helps you compare easily what is greater and lesser.

=> 5 tens and 0 ones.
5000 => is a 4 digit whole number, which means it as a place value of 5000
=> 5 thousands 0 hundreds, 0 tens and 0 ones.
5000 is 100 times greater than 50.
=> 50 x 100 = 5000
