7-2(2+5)-8
7-2(7)-8
5(7)-8
When there is a bracket it means, you are supposed to multiply the number in front of it with the number in the bracket. So....
5 x 7 -8= 35-8
= 27

Thus the answer is 27

For the mean, add together all of the numbers together (let's call the total x) and count how many numbers there are. (let's call this number y). divide x by y, and that is your mean. for the median, put all the numbers in order, and the median is the number in the middle. if there are two numbers in the middle, add them together and divide them by 2.
