I still can't see how they get the answer

Here is an easy exercise that must be done in your head only. Do NOT use paper and pencil or a calculator. Try to add up the following numbers as quickly as you can. Take 1000 and add 40 to it. Now add another 1000. Now add 30. Add another1000. Now add 20. Now add another 1000. Now add 10. What is the total?

I didn't get it right at first, either. But our brains are fooling us into thinking that the smaller numbers are actually 100s, not 10s.

God, that is really strange. I feel so stoopid now.
