Hey there!
Here's the answer.
(1-6i)-(-3-8i) --> Write the problem.
(1-6i)+(3+8i) --> Distribute -1 into -3-8i.
1+3-6i+8i --> Gather the constant terms together and the i terms together.
4+2i Add 1 and 3, also add -6i and 8i.
So the answer is 4+2i.
Hope it helps!

That is just a subtraction in which there are two separate terms, each needing to be subtracted from the corresponding other set.
so 1 - - 3 = 4
and -6i - -8i = 2i
That gives 4+2i for the answer.

1-6i-(-3)-(-8i)=1-6i+3+8i=1+3+8i-6i=4+2i=2(i+2)

4 + 2i = 2(2 + i)
