# What is each sum or difference of (7-2i)+(-3+i)?

Dec 21, 2016

I got: $4 - i$

#### Explanation:

We can get rid of the brackets and write it as:
$7 - 2 i - 3 + i =$
Now we can add or subtract similar terms (the ones with $i$ and the ones without):
$\left(7 - 3\right) + \left(- 2 i + i\right) = 4 - i$
