Final answer:
To subtract complex numbers, subtract their real parts and their imaginary parts separately.
Step-by-step explanation:
To subtract complex numbers, we subtract their real parts and their imaginary parts separately. The given complex numbers are (3+3) and (13+15). We subtract their real parts: 3 - 13 = -10, and their imaginary parts: 3 - 15 = -12.
So, the result is -10 - 12i.
