Adding Complex Numbers: (8 + 8i) + (12 + 2i)
This article explains how to add complex numbers using the example of (8 + 8i) + (12 + 2i).
Understanding Complex Numbers
A complex number is a number that can be expressed in the form a + bi, where:
- a and b are real numbers.
- i is the imaginary unit, defined as the square root of -1 (i² = -1).
a is called the real part and b is called the imaginary part of the complex number.
Adding Complex Numbers
To add complex numbers, we simply add the real parts and the imaginary parts separately.
Step 1: Identify the real and imaginary parts of each complex number.
- (8 + 8i): Real part = 8, Imaginary part = 8
- (12 + 2i): Real part = 12, Imaginary part = 2
Step 2: Add the real parts together and the imaginary parts together.
- Real part: 8 + 12 = 20
- Imaginary part: 8 + 2 = 10
Step 3: Combine the results to get the final complex number.
- (8 + 8i) + (12 + 2i) = 20 + 10i
Conclusion
Therefore, the sum of (8 + 8i) and (12 + 2i) is 20 + 10i.
