<span>A complex number is a number of the form a + bi, where i = and a and b are real numbers. For example, 5 + 3i, - + 4i, 4.2 - 12i, and - - i are all complex numbers. a is called the real part of the complex number and bi is called the imaginary part of the complex number.</span>
We can distribute the negative to get 8 + 6i + 2 - 7i, and we can simplify that to get 10 - i.
