(adsbygoogle = window.adsbygoogle || []).push({}); Very tricky math! Note: This 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?


Now i know what your thinking that was easy right.

so you got 5000 yh?

wrong answer is 4100 look for yourself

Wow... I'm majoring in Math and got 5,000 hahaha. Yet I've been able to get A+ is Calculus 1 and 2 easy, but can't do this... Oh well, guess that's what happens when you do things quickly.

I think most of us can add numbers together.
