Question

Give an example to show that subtraction of a complex number is not

commutative.​

Answer 1

Step-by-step explanation:

Here's an example. Since -4 does not equal to 4, subtraction is not commutative. Commutative property states that a+b=b+a or ab=ba.

Answer 2

Answer:

Example : (6 + i5) - 8i = 6 + i(5 - 8) = 6 - i3 < From the above we can see that 6 + i5 is a complex number, -i8 is a complex number and the subtraction of these two numbers is 6 - i3 is again a complex number. Associative property does not hold true for subtraction of complex-numbers.
