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
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.
In any addition sum, such as 3 + 4 = 7, the addends, otherwise known as summands, are the numbers which are to be added together to create the sum.Addends are what you add to create the final answer (the sum). For example, in the problem 9+8=17, 9 and 8 are the addends and 17 is the sum.
(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

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
