This probably refers to how to handle computations with the set of Complex Numbers (which is a combination of the set of real numbers and imaginary numbers), rather than just complicatedcalculations, or calculations which are very involved and as-such appear very complex (which is a different thing than Complex Numbers).

Calculators, probably in the 1980's (I know for a fact the HP 48 calculator circa 1992 handled complex and imaginary numbers) helped people perform calculations with complex numbers, without having to figure conjugates, angles, etc. on paper. Complex number computing was long before that. I know that FORTRAN (developed by IBM and released in 1957) could handle complex number calculations. FORTRAN was designed specifically for scientific and engineering calculations. Check out the Wikipedia article.

Georgie was fascinated by her friend's ability to do complex mathematical calculations in her head.
No but it can still do them and then you have it when you need more complex problems answered.
