i is the symbol representing √(-1).

Whole numbers and fractions, including irrational numbers like π, are called "real" numbers.

i is called an "imaginary" number, which is a different type of numbers.

All the real numbers and imaginary numbers form the set of complex numbers.

Examples:  √(-9)  =  √(9)√(-1)  =  3√(-1)  =  3i  (another imaginary number)

Complex numbers can be formed by adding and subtracting real numbers with imaginary numbers, such as

5 + 7i, -2 + i, and 7 - 9i.
