48 and 32; 48+32=80 48-32=16.
To get the range of a group of numbers you subtract the smaller number from the larger one The mean is the "average" for a group of numbers to get the mean you add all the numbers together. Then divide that number by the number in the group.
Subtract the absolute value of the smaller number from the absolute value of the larger number. The answer will have the sign of the larger numbers.

If both numbers are positive, simply add them as you learned in 4th grade. If both numbers are negative,simply add them but add a minus to the answer. If one is positive and the other negative, ignoring the signs,subtract the smaller from the larger and add the sign of the larger to your answer.
In order to sum two numbers where one is negative, you subtract the smaller from the larger and take the sign of the larger Ans: -30
