1. `A=5+6i,B=-2+3i,C=1-3i`
Find A + B

Solution:
Here `A=5+6i,B=-2+3i,C=1-3i`


`A+B`

`=(5+6i)+(-2+3i)`

`=5-2+6i+3i`

`=3+9i`

2. `A=5+6i,B=-2+3i,C=1-3i`
Find B + C

Solution:
Here `A=5+6i,B=-2+3i,C=1-3i`


`B+C`

`=(-2+3i)+(1-3i)`

`=-2+1+3i-3i`

`=-1`

3. `A=5+6i,B=-2+3i,C=1-3i`
Find A + C

Solution:
Here `A=5+6i,B=-2+3i,C=1-3i`


`A+C`

`=(5+6i)+(1-3i)`

`=5+1+6i-3i`

`=6+3i`
