What do all the numbers on a dartboard add up to?

Answer 1

The numbers on a dartboard run from 1 to 20 with no duplicates. Think of pairing them up like this: 1 and 20, 2 and 19, 3 and 18... and so on to 10 and 11.
Each pair adds up to 21.
There are ten pairs total.
So the total of all the numbers on a dartboard is 210.
