Aiko is finding the sum (4 + 5i) + (–3 + 7i). she rewrites the sum as (–3 + 7)i + (4 + 5)i. which statement explains the mathematical property that she made an error using?
aiko incorrectly used the commutative property by changing the order of the two complex numbers.
aiko incorrectly used the associative property by changing the order of the two complex numbers.
aiko incorrectly used the identity property by combining the real number and the coefficient of the imaginary part.
