“complex” doesn’t mean “complicated”; it means that two types of numbers, real and imaginary, have bonded together to form a complex, a hybrid number like 2 + 3i. Complex numbers are magnificent, the pinnacle of number systems. They enjoy all the same properties as real numbers — you can add and subtract them, multiply and divide them — but they are better than real numbers because they always have roots. You can take the square root or cube root or any root of a complex number, and the result will still be a complex number.
