Is 0 a real number in math?

Question:- Is 0 a real number in math?

Answer: Indeed, zero is among the veritable real numbers in mathematics. The set of real numbers consists of all the positive numbers, the negative numbers as well as the zero. Zero occupies a special rank as it is an additive identity, or as it is put, the sum of zero and some quantity is the same as this quantity of the required kind. Moreover, zero is utilized as a reference or the starting point on the number line that divides the number between positive and negative.

Zero is very important in mathematics and has its use in different topics and calculations. It is the only number that when multiplied by any other number, results in that same number or itself. It is also the additive identity to itself which makes zero the identity element of the group under addition. Also, zero is a critical sign in algebra, calculus, and other high-level mathematical areas since it has obvious and not-so-apparent attributes that are applied and investigated in these areas.
