``` (A_REP_COLORED) OPERATOR (B_REP_COLORED) ```
The real components of the two complex numbers are `A_REAL` and `B_REAL`, respectively, so the real component of the result will be ``` A_REAL_COLORED OPERATOR \color{BLUE}{negParens(B_REAL)} ```, which equals `ANSWER_REAL`.
The imaginary components of the two complex numbers are `A_IMAG` and `B_IMAG`, respectively, so the imaginary component of the result will be ``` A_IMAG_COLORED OPERATOR \color{BLUE}{negParens(B_IMAG)} ```, which equals `ANSWER_IMAG`.
The result is `complexNumber(ANSWER_REAL, ANSWER_IMAG)`; its real component is `ANSWER_REAL` and its complex component is `ANSWER_IMAG`.
