p+qi and r+ti are two complex numbers.

To add these two complex numbers we add the real parts and imaginary parts of both the numbers separately.

(p+qi) + (r+ti ) = (p+r ) + (q+t)i

Example:

(3+4i ) +(2+5i )
= (3+2) + (4+5)i
=(5+9i )

2. Subtraction

p+qi and r+ti are two complex numbers.
To subtract these two numbers, we will subtract the real part of second number from the real part of the first number and imaginary part from imaginary part.

(p+qi ) – (r+ti ) = (p-r ) + (q-t)i

Example:

(5+3i) – (4+i)
= (5-4) + (3-1)i

## Check point

1.) ( -13 + 4i) + ( 7 + 4i)
2.) (-15 + 7i) – (2 + 3i)
3.) (-7 + 3i) + (- 2 + 5i)
4.) 4 – (3 + 2i)
5.) (2 – 3i) + (4 + 7i)

‘Practice makes a man perfect’ holds true for no other field better than for math. A middle or high school student must set aside a minimum of an hour for math every day. Other than textbooks, worksheets help you revise and understand concepts better.
