What is a number?
In mathematics, a number is a value that we everyday call a number. Why not just call it numbers?, because identical numbers are only 1, 2, 3, and so on.
Numbers are broadly divided into two types, the first real numbers (real numbers) and imaginary numbers (imaginary numbers).
Real numbers are numbers in the form a/b (rational number) and sqrt[c](d) (irrational number) where b is non-zero and the result of sqrt[c](d) is not an integer. Whereas,
An imaginary number is a number in the form sqrt(d) where d is a negative number.
From the explanation above it should be clear. This is a general explanation of numbers.
