In mathematics there is more than one type of "average". However the usual meaning, unless stipulated otherwise, is the mean average, so I will assume this is what you mean (no pun intended).
The mean is calculated by dividing the sum of the values by the number of values.
Here the sum is: -13.52 + -15.88 + 500 + 2516 = 2986.6.
The number of values is: 4.
The mean is therefore: 2986.6 / 4 = 746.65.
The total sum is 2516
They both add up to 2516
17 plus 9 plus 6 plus 16 is a single number whose value is 38. The average of one number is itself.
100000 + 45000 + 15000 + 15000 + 15000 +10000 = 200000 Since there is only one number, the average is that number, namely 200000
30/3=10
The total sum is 2516
They both add up to 2516
Estimate: 400+1600 = 2000 Actual: 375+1588 = 1963
375 + 1588 = 370 + 1590. These are not easy numbers to wok with so move 10 from 370 to 1590. = 360 + 1600 = 1960.
The answer is 1963. Simply add the numbers together arithmetically as you would for the problem two plus two. To check your work, a calculator is the best option.
6.38 is the average of the three numbers.
The average of 0.3 and 3 and 30 is 11.1

17 plus 9 plus 6 plus 16 is a single number whose value is 38. The average of one number is itself.
