They are used in place of an unknown number or value.
The PLACE VALUE.
No number is known as the place value number. Rather it is the system of numbering used whereby a particular digit will change its value depending on its position within the number. eg; 200 and 2,000. The 2 in the first number has a value of two hundred while in the second it has a value of two thousands. It depends where in the positional notation the number is that assigns its value.
The 'zero' symbol is used as a place value holder,and it can hold any place.
It is used for positional place value purposes so as for example to show that 203 is larger than 23

Align the numbers according their place values. Go from left to right (decreasing place values) until the face values of the numbers are different. Then the number with the larger face value in that place is the larger number.
