Mathematics
There was once a teacher who wanted to punish his misbehaving students by torturing them with a very boring math problem. he told them to get out a piece of paper and add up all the number 1 to 100. the students groaned but got to work adding up all the numbers. imagine the teacher's surprise though when fred (who was a big goof off but very good in math) raised his hand after about 30 seconds and said i've got it. and he did. can you, like fred, figure out a way to solve this problem simply, without having to sit there and add numbers for an hour.

Ответ:
If you look at numbers 1 to 100, and matched up numbers, like this:
1+99
2+98
3+97
and so on, you would always get 100. So, when you add up all the numbers besides 100, you will get 100.
Hope I helped, sorry if I'm wrong.
