Below are sample questions representative of the exercises included on this worksheet and related ALG2.23 Complex Number Arithmetic skill assessments:

Problem 1Difficulty: Mastery
Simplify (-2i) / (-3 + 3i) + (1 - i) / (3 + i).
A8/15 - 1/15i
B1/15 + 2/15i
C-2/15 - 1/15i
D-8/15 + 11/15i
Solution & Explanation:Find each quotient first: (-2i) / (-3 + 3i) = -1/3 + 1/3i and (1 - i) / (3 + i) = 1/5 - 2/5i. Then add the results to get -2/15 - 1/15i.
Problem 2Difficulty: Mastery
Simplify (2 + 2i) / (3 + i) - (1 + 4i) / (1 - 3i).
A-3/10 + 11/10i
B19/10 - 3/10i
C3/2 + 1/10i
D-1/2 + 3/10i
Solution & Explanation:Find each quotient first: (2 + 2i) / (3 + i) = 4/5 + 2/5i and (1 + 4i) / (1 - 3i) = -11/10 + 7/10i. Then subtract the results to get 19/10 - 3/10i.
Problem 3Difficulty: Mastery
Simplify (-2 + 4i) / (-2 - i) + (1) / (1 - i).
A1/2 - 3/2i
B21/10 - 7/10i
C-1/2 - 5/2i
D1/2 - 5/2i
Solution & Explanation:Find each quotient first: (-2 + 4i) / (-2 - i) = -2i and (1) / (1 - i) = 1/2 + 1/2i. Then add the results to get 1/2 - 3/2i.
