"WebHow to solve addition of complex numbers? To add two or more complex numbers, we simply have to add the real and imaginary parts separately. This is similar to adding polynomials, where we add like terms. Therefore, if we have the numbers z_ {1}=a+bi z1 = a+ bi and z_ {2}=c+di z2 = c +di, their addition is equal to: " - How to solve for complex numbers
