Adding Complex Numbers: (-4 + 2i) + (6 - 3i)

This article will demonstrate how to add two complex numbers: (-4 + 2i) + (6 - 3i).

Understanding Complex Numbers

Complex numbers are numbers that consist of two parts: a real part and an imaginary part. They are typically written in the form a + bi, where:

  • a is the real part (a real number)
  • b is the imaginary part (a real number)
  • i is the imaginary unit, defined as the square root of -1 (i² = -1)

Adding Complex Numbers

To add complex numbers, we simply add the real parts and add the imaginary parts separately.

Step 1: Separate the real and imaginary parts

  • (-4 + 2i) has a real part of -4 and an imaginary part of 2.
  • (6 - 3i) has a real part of 6 and an imaginary part of -3.

Step 2: Add the real parts and the imaginary parts

  • Real part: -4 + 6 = 2
  • Imaginary part: 2 + (-3) = -1

Step 3: Combine the results

The sum of (-4 + 2i) + (6 - 3i) is 2 - i.

Conclusion

Adding complex numbers is straightforward. We simply combine the real and imaginary components separately. In the case of (-4 + 2i) + (6 - 3i), the sum is 2 - i.
