Complex Numbers
Complex numbers are numbers that have a real part and an imaginary part, expressed in the form a + bi, where 'a' is the real part and 'b' is the coefficient of the imaginary unit 'i', which is defined as the square root of -1. Understanding complex numbers is essential for performing operations involving them, such as addition, subtraction, multiplication, and division.

Standard Form of Complex Numbers
The standard form of a complex number is expressed as a + bi, where 'a' and 'b' are real numbers. After performing operations on complex numbers, it is important to express the result in this form for clarity and consistency. This involves combining like terms and ensuring that the imaginary unit 'i' is properly represented.
