# (4-5i) -(6-i) = 4-5i -6+i = -2-4i #
Explanation:
To add or subtract complex numbers we just add or subtract the real and imaginary components separately, thus:
# (4-5i) -(6-i) = 4-5i -6+i #
# \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ = 4-6-5i +i #
# \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ = -2-4i #
