As can be seen by the grouping in the
original problem, and taking into account
the minus sign before this, this is supposed to be
-(1/3)(1-3i)
= -[(1/3)(1) + (1/3)(-3i)]
= -(1/3 - i)
= -1/3 + i
3i + [1/2] - [1/3](1-3i) + 2
= 3i + 1/2 - 1/3 + i + 2
= 2 + 1/2 - 1/3 + 3i + i
= 5/2 - 1/3 + 4i
= 13/6 + 4i
or: 2 1/6 + 4i
