Adição, subtração, multiplicação e divisão de números complexos - Professora Angela

Hi everyone!! In today's video we have examples of addition, subtraction, multiplication, and division operations with complex numbers. Complex numbers are numbers composed of a real part and an imaginary part (z=a+bi). This number, represented by the letter (i), is called the imaginary unit. In addition and subtraction operations with complex numbers, we add or subtract, respectively, their real and imaginary parts. In the multiplication of complex numbers, we can use the distributive property of multiplication. In the division of complex numbers, we can write the quotient as a fraction, then multiply both terms of this fraction by the complex conjugate of the denominator.
