How do you add subtract multiply and divide complex numbers and polynomials

A complex number is the sum (or difference) of two parts: real and imaginary.To add or subtract two complex numbers, need to add\subtract separately the real part and imaginary separately. In the end, you will receive the imaginary and real part of the result. 

More difficult to divide complex numbers. 1. We must find the complex conjugate of the denominator 2. Then, we must multiply the numerator and denominator by that conjugate and simplify the expression.The complex conjugate have the part equal to given, and the imaginary part is opposite to given.

To multiply complex numbers, we must multiply it like the two expressions in brackets, and simplify the result.

Addition subtraction and multiplication of polynomials is also made as expressions in parentheses between them. During the operation it is necessary to cause such members.To divide the polynomial by the polynomial you need to record them so as if you divide the numbers in a column, and perform the division by the same rules.
