4) What does this symbol mean?"!"

Parallel

Factorial

Proportionate

The symbol "!" in mathematics represents the factorial operation. Factorial is a mathematical function that multiplies a given number by all of the positive integers less than it. For example, 5! (read as "5 factorial") is equal to 5 x 4 x 3 x 2 x 1, which equals 120. Therefore, the correct answer is "Factorial."
