When a symbol is used for a number it could be any symbol at all. It could be a letter from the Roman or Greek alphabet, upper case or lower case. It could also be any random symbol that you like provided that it is not a "reserved" symbol. By that I mean you cannot use "+" as a symbol since that might be very confusing!
it is any letter or mathematical symbol that represent a number or a set of number
The greater than symbol is typically a mathematical symbol declaring that one given value or number is greater than another given value or number. One would use this symbol for certain mathematical applications, as well as to indicate in any circumstance that one things value is greater than another.
Q is the set of all rational numbers. The letter Q is used because rationals can be expressed as a quotient of two integers. Any letter from the Greek or Latin alphabet may be used as a symbol for an individual rational number.
Well, you can create the flowchart to you, but here is the basic outline of what needs to be done. Call your number - the number you want to test - "n". Divide it by each integer in turn, starting with 2, and ending with "n-2". What matters here is the remainder of the division. If at any point you get a remainder of zero, that means you have found a smaller factor, and the number is NOT a prime - it is composite. You can end the process immediately. If you do all the divisions and DON'T get a remainder of zero at any point, there is NO smaller factor, so your number is prime. (To make the process run faster, you can actually stop once your factor is greater than the square root of "n".)

The symbol for number is #
I will assume that you mean " to the power of two ". A symbol for any n-power is to put the number (n) on the side, above the number. Like this: nn.
No. Radical(1.21) = 1.1, for example, is rational.
Any mathematician will use the number pi (and its symbol) sooner or later - it is a number used extensively in many different areas of mathematics.
