Step 1

For example:

Let the first complex number is$5+2i$

And the second complex number is$8+7i$

To add both the complex numbers:

$(5+2i)+(8+7i)$

Group the real parts together and imaginary parts together:

$(5+8)+(2i+7i)$

Add the like terms:

$\left(13\right)+\left(9i\right)$

Hence,

$(5+2i)+(8+7i)=(13+9i)$

For example:

Let the first complex number is

And the second complex number is

To add both the complex numbers:

Group the real parts together and imaginary parts together:

Add the like terms:

Hence,

Step 1

Calculation:

1)$5+2i$

2)$8+7i$

Add:$\left(1\right)+\left(2\right)$

$=(5+2i)+(8+7i)=(5+8)+(2+7)i$

$=13+9i$

Result:

Rectangular form:

$z=13+9i$

Calculation:

1)

2)

Add:

Result:

Rectangular form:

Step 1

(5+2i)+(8+7i)

Group the real part and the imaginary part of the complex number

(a+bi)

=(5+8)+(2+7)i

5+8=13

2+7=9

=13+9i
