Math question 1a?

Associative Property of Addition tells you that you can add a group of numbers in any order and get the same result. A simple example
(x + y) + z
is the same as:
x + (y + z)
In your case you have to be careful about the negative signs. Recall that subtraction is the same as adding the opposite, so:
(6 - 2i) - 3i
Is the same as:
[6 + (-2i)] + (-3i)
Now if you group the "i" together we get:
6 + [(-2i) + (-3i)]
And then simplifying this gives us:
6 + (-2i - 3i)
This is answer B from your multiple choice.
