Do this sum in your head and don't use a calculator or pen and paper. Just give it a go.

Take 1000 and add 40 to it. Now add another 1000. Now add 30. Add another 1000. Now add 20. Now add another 1000. Now add 10. What is the total?

Don't know
5000
6000
4100

By the by, if your posting your answer, don't go into too much detail as it might take away from other peoples theories.

I posted this before, just thought it might be fun to put it in this section, good luck.

4100 - This was easy - is there a catch or am I missing something?
3000
(attempt 2) 2100
This only works when it is pronounced, rather than written down. The latter way makes it very easy to give the correct answer, whereas not a few make a mistake the other way.
This is a well known one intended to try and trick people, but better done aurally. The answer is, of course, 4100 but so many people will answer 5000 because they are fooled by what they expect to hear.
