If you simply add numbers the answer is the sum of those numbers.
221
if you add all the numbers up and dived them by the numbers of numbers
10 + 23 = 33 Lowest possible real number 97 + 86 = 183 Highest possible real number 02 + 13 = 15 Lowest possible number 97 + 86 = 183 Highest possible number
To add numbers with significant figures, first add the numbers as usual. Then, round the final answer to match the number with the least number of decimal places in the original numbers.
When adding numbers with significant figures, the result should be rounded to the least number of decimal places in the original numbers. Add the numbers as usual, then round the result to match the least precise number in the calculation.

Doing it mentally, the easiest method is usually to pair the greatest with the least and add them up, then add the resultant numbers using the same method until you end up with the sum.

None add up to 30; you would need at least three 6-sided die with numbers 6-11 to add to 30.
When adding numbers with significant figures, the result should be rounded to the least number of decimal places in the original numbers. Add the numbers as usual, then round the result to the appropriate number of significant figures.
2000.The smallest four-digit number there can be is 1000. So, add 1000 and 1000 to get 2000, then least sum you can get when adding two four-digit numbers.
We don't have a prayer of answering this question until we know what numbers are in the set, and neither do you.
It will enable you to add and subtract fractions with unlike denominators.
10+23 = 33
