Complex numbers are made up of real numbers and imaginary numbers. They are usually written in the form ( a + bi ). Let’s break that down:
Real Numbers (a): These are the regular numbers you see every day. Examples include numbers like ( 3 ), ( -2 ), or ( 0.5 ).
Imaginary Unit (i): The letter ( i ) is called the imaginary unit. It represents the square root of (-1). This means that ( i^2 ) is equal to (-1).
Complex Numbers (a + bi): When you put together a real number ( a ) (like ( 2 )) with an imaginary number ( bi ) (such as ( 3i )), you create a complex number. For example, ( 2 + 3i ) is a complex number.
In the expression ( a + bi ), ( a ) is the real part, and ( b ) is the imaginary part. So, complex numbers are a cool mix of real and imaginary parts!
