There are three sets of complex numbers worksheets:
Examples, solutions, videos, and worksheets to help Algebra II students learn how to add and subtract complex numbers.
There are two sets of add & subtract complex number worksheets.
Adding and subtracting complex numbers involves combining their real and imaginary parts separately. Complex numbers are in the form a+bi, where a is the real part and b is the imaginary part. Here’s how to add and subtract complex numbers:
Adding Complex Numbers:
To add two complex numbers a1 + b1i and a2 + b2, follow these steps:
Add 3 + 2i and 1 - 5i
Real parts: 3 + 1 = 4
Imaginary parts: 2 - 5 = -3
3 + 2i + 1 - 5i = 4 - 3i
Subtracting Complex Numbers:
To subtract two complex numbers a1 + b1i and a2 + b2, follow these steps:
Subtract 3 + 2i from 1 - 5i
Real parts: 1 - 3 = -2
Imaginary parts: -5 - 2 = -7
1 - 5i - (3 + 2i) = -2 - 7i
