WebOct 25, 2024 · To add and subtract complex numbers, you just combine the real parts and the imaginary parts, like this: (5 + 3 i) + (2 + 8 i) = (5 + 2) + (3 + 8) i = 7 + 11 i This is similar to combining “like terms” when you add polynomials together: (3 x + 2) + (5 x + 7) = 8 x + 9 WebApr 13, 2024 · Here’s how you can identify the real and imaginary parts of a complex number: Look for the terms not multiplied by i: these are the real parts. Look for the terms multiplied by i: these are the imaginary parts. For example, consider the complex number 5 + 3i. The real part is 5, and the imaginary part is 3i. To simplify complex numbers ...
WebAs long as it is clear what the i is affecting, you can do both. EG (2 + 3i) + (4 + 5i) = (2 + 4) + i(3 + 5) or (2 + 4) + (3 + 5)i However, there are conventions. When we simplify the above we would normally write 6 + 8i, not 6 + i8, but both are fine, but the second one just looks weird.
