What is alpha numeric characters?

Alphanumeric characters means any combination of letters and digits. Sometimes other special symbols are allowed, too - so alphanumeric may sometimes be understood to mean a combination of just about any type of symbols.


Roman numerals use how many symbols?

The most commonly used Roman numerals can be made from a combination of seven (7) different symbols, whcih are...I = 1V = 5X = 10L = 50C = 100D = 500M = 1000Using these symbols any number from 1 to 3999 can be represented.


How many different symbols for numbers are there?

There is no specific number of symbols that can be used. You can use any letter of any alphabet.


Are there any special symbols used in cryptography?

Yes, cryptography employs various special symbols and characters, including mathematical symbols (like modulo, exponentiation), operators (such as XOR for bitwise operations), and placeholders (like "K" for keys or "P" for plaintext). Additionally, many cryptographic algorithms utilize specific encoding formats (like Base64) and character sets (like hexadecimal) to represent binary data. These symbols are essential for ensuring secure communication and data integrity.


What is the combination of real numbers in math?

It depends on the combination. Real numbers are closed with respect to arithmetical operations (+, -, *, /), as well as integer powers (exponents). So a combination of real numbers using any of these operators will yield a real number. But the set is not closed with respect to some fractional powers - for example, the square root of a negative number is not real.It depends on the combination.
