Jun 01, 2018 · So, thinking of numbers in this light we can see that the real numbers are simply a subset of the complex numbers. The conjugate of the complex number \(a + bi\) is the complex number \(a - bi\). In other words, it is the original complex number with the sign on the imaginary part changed. Here are some examples of complex numbers and their ...
• The answer is one more step. We can add a real number to an imaginary number. The result is called a complex number. This is the end of the line because it turns out that every possible operation with every possible complex number results only in other complex numbers. We say that complex numbers make the numbers complete.
