When you do not know the value of a particular number, the most usual symbol used in place of that number is the letter x.
The PLACE VALUE.
They are used in place of an unknown number or 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.
Place value charts are tools used to visually represent the value of digits in a number based on their position. Each column in the chart corresponds to a specific place value, such as ones, tens, hundreds, and so on. For example, in the number 345, the digit 3 is in the hundreds place, meaning it represents 300, while the 4 in the tens place represents 40, and the 5 in the ones place represents 5. This organization helps in understanding how each digit contributes to the overall value of the number.

There is not a missing number from the number sequence. This is used in math.

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.

a variable
The word round in maths means to find the nearest value of a number.
It is used for positional place value purposes so as for example to show that 203 is larger than 23
The use of the digit 0 in a number is to indicate place value. It enables you to distinguish between 405 and 45, for example.
Place value is not used in the Roman numeral system.
