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.
