How do you average together negative and positive numbers?

Add the negatives on one group, add the positives on another group. Subtract the smaller result from the greater number (whether is negative group or positive) then divide your result between the addends.

EX. average of -16, -28, 14, -10, 30

-16 + -28 + -10= -54

14 + 30= 44

-54 - 44= -10

-10 ÷ 5 = -2

*note : 5 is the addends (amount of numbers listed)
