Number elves

Once upon a time, there was a magic forest. When you walked in the forest you could see many number elves. The elves flew everywhere, and their body were shining when they were happy. The number elves lived in a special cave. It was called Math cave. If you wanted to get into the cave, you must answer a Math question. The door would not open unless you got the right answer. Now, let’s think about it: What is 1+2+…+99+100? Do you know?
