Mind twister

This exercise must be done in your head only . Do NOT use paper and pencil or a calculator. Try it!
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?

Did you get 5000 ?

Wrong!

Correct answer is 4100!!!

I tried paper and I still get 5000. I must be brain-damaged.

At the final step, when you add 4090 and 10, it will give 4100... but our mind will automatically take it as 5000...
