Adding and Subtracting Complex Numbers
Add like terms
Find the sum of the real components.
Find the sum of the imaginary components (the components with the i after them).
Adding Rule:
(m+ni) + (p+qi) = (m+p) + (n+q)i
Examples:
Subtract like terms
Find the difference of the real components.
Find the difference of the imaginary components (the components with the i after them).
Subtracting Rule:
(m+ni) – (p+qi) = (m-p) + (n-q)i
