Adding Complex Numbers: (10 - 7i) + (6 + 9i)
This article will guide you through the process of adding the complex numbers (10 - 7i) and (6 + 9i).
Understanding Complex Numbers
Complex numbers are numbers that can be expressed in the form a + bi, where:
- a is the real part of the complex number.
- b is the imaginary part of the complex number.
- i is the imaginary unit, where i² = -1.
Adding Complex Numbers
To add complex numbers, we simply add their real and imaginary parts separately.
-
Identify the real and imaginary parts:
- In (10 - 7i), the real part is 10 and the imaginary part is -7.
- In (6 + 9i), the real part is 6 and the imaginary part is 9.
-
Add the real parts:
- 10 + 6 = 16
-
Add the imaginary parts:
- -7 + 9 = 2
-
Combine the results:
- The sum of the complex numbers is 16 + 2i.
Conclusion
Therefore, (10 - 7i) + (6 + 9i) = 16 + 2i.
