How to fill out operations with complex numbers

1. To fill out operations with complex numbers, follow these steps:
2. Start by understanding the basic properties of complex numbers. Complex numbers consist of a real part and an imaginary part, denoted as a + bi, where a is the real part and bi is the imaginary part with 'i' being the imaginary unit.
3. Addition: To add two complex numbers, simply add their real parts and imaginary parts separately. For example, to add (3 + 2i) and (1 - 4i), add 3 + 1 = 4 for the real part, and 2i - 4i = -2i for the imaginary part. Therefore, the sum is (4 - 2i).
4. Subtraction: To subtract two complex numbers, subtract their real parts and imaginary parts separately. For example, to subtract (3 + 2i) from (1 - 4i), subtract 3 - 1 = 2 for the real part, and 2i + 4i = 6i for the imaginary part. Therefore, the difference is (2 + 6i).
5. Multiplication: To multiply two complex numbers, use the distributive property. For example, to multiply (3 + 2i) and (1 - 4i), distribute 3 to both terms inside the second parentheses and 2i to both terms inside the first parentheses. Then, simplify the expression. The result is (11 - 10i).
6. Division: To divide two complex numbers, use the conjugate. The conjugate of a complex number a + bi is a - bi. Multiply the numerator and denominator by the conjugate of the denominator and simplify the expression. For example, to divide (3 + 2i) by (1 - 4i), multiply both numerator and denominator by (1 + 4i). After simplification, the result is (-2/17 + 14i/17).
7. These are the basic steps to fill out operations with complex numbers. Remember to apply the rules of arithmetic and always simplify your answers.
