Real numbers can be positive or negative, and include the number zero. They are called real numbers because they are not imaginary, which is a different system of numbers. Imaginary numbers are numbers that cannot be quantified, like the square root of -1.

Is 0 a rational number?

Yes, 0 is a rational number. Since we know, a rational number can be expressed as p/q, where p and q are integers and q is not equal to zero. Thus, we can express 0 as p/q, where p is equal to zero and q is an integer.

Who invented factorial?

The factorial function can be found in various areas of mathematics, including algebra, mathematical analysis, and combinatorics. Starting in the 1200s, factorials were used to count permutations. The notation for a factorial (n!) was introduced in the early 1800s by Christian Kramp, a French mathematician.

How do you explain factorial to a child?
