All righty, so i like math, specifically geometry, and i wanted to make a page where you can post any tough math problems..then the first person who answers that problem right "wins" a point...those who get 3 points will start being recognized on this page. I will edit this post to show "hall of famers".
3 points: Arithmalete
5 points: Rising Star
10 points: Math God
Hope you guys like this, i'll start off...
A set of integers has an average of 7. When you add the number 10 to the set of integers, the average goes up by 0.5. When you add -3 to the new set of integers, the average goes down by 1.5 (it goes down by 1.5 from the 2nd average, not the original average of 7).
How many integers were in the original set, before anything was added?
