Just add the real part and the imaginary part separately.
To form the additive inverse, negate all parts of the complex number → 8 + 3i → -8 - 3i The sum of a number and its additive inverse is 0: (8 + 3i) + (-8 - 3i) = (8 + -8) + (3 + -3)i = (8 - 8) + (3 - 3)i = 0 + 0i = 0.
It would be 8 minus 9i or 8-9i
Take the sum of the numbers divided by the number of numbers. Mean = (7+8+8+2+10+8+7)/7 = 7.14
i have no clue Sum of 8 and 6=14 and product of "8 and sum of 8 and 6"=112
While some may think the answer is 6, in fact it is not. First lets multiply 2x2 and we will get a sum of 4.Next we will take the sum of 4 and use the next 2 in the equation as 4x2; 4X2 equals 8. 8 is your correct answer.
(7 + 3i) + (8 + 9i) = (7 + 8) + (3i + 9i) = (7 + 8) + (3 + 9)i = 15 + 12i Which can also be written as: 15 + 12i = 3(5 + 4i).
(8+6i)-(2+3i)=6+3i 8+6i-2+3i=6+9i
To form the additive inverse, negate all parts of the complex number → 8 + 3i → -8 - 3i The sum of a number and its additive inverse is 0: (8 + 3i) + (-8 - 3i) = (8 + -8) + (3 + -3)i = (8 - 8) + (3 - 3)i = 0 + 0i = 0.

Find the product of 7 and the sum of 8 and 10
The sum of 1 and 7 is 8. That is, 1 + 7 = 8
8 + 7 = 15
15
The sum is: 8
