Is √ a real number?

√2 is irrational. Now we know that these irrational numbers do exist, and we even have one example: √2. It turns out that most other roots are also irrational. The constants π and e are also irrational.

Is zero a number Yes or no?

0 (zero) is a number, and the numerical digit used to represent that number in numerals. It fulfills a central role in mathematics as the additive identity of the integers, real numbers, and many other algebraic structures. As a digit, 0 is used as a placeholder in place value systems.

What numbers are real numbers?
