Answer 2

• When adding complex numbers, add like terms according to the normal rules. Add constants to constants, variables to variables, and imaginary numbers to imaginary numbers.

Question 3

• When subtracting complex numbers, subtract like terms according to the normal rules, paying attention to sign changes across parentheses as you combine constants with constants, variables with variables, and imaginary numbers with imaginary numbers.

Answer 3

• When subtracting complex numbers, subtract like terms according to the normal rules, paying attention to sign changes across parentheses as you combine constants with constants, variables with variables, and imaginary numbers with imaginary numbers.
