Perform the addition: (3 + 2i) + (4 - 5i)

• 8 - 4i

• 6 - 2i

• 5 - 3i

• 7 - 3i

Simplify. Write your answer in the form  $a+bi$  .

 $\left(2+4i\right)-\left(1-2i\right)$  

•  $3+2i$  

•  $1-2i$  

•  $1+6i$  

•  $10$  

Subtract: (-3 + 2i) - (6 - 5i).

• 9 - 3i

• -9 + 7i

• -9 - 7i

• 3 - 7i

Add the following

(-2+3i) + (-7-3i)

-30i+10=-50

• 2

• 3

• 6

• 8

Calculate: (12 + 3i) + (6 - 2i)

• 18 + i

• 9 + i

• 18 - i

• 15 + i

What is the result of adding (3 + 2i) and (5 - 4i)?

• 10 - 6i
