Default Neat little math problem
Note: This must be done in your head only. Do NOT use paper and pencil or a calculator.

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? The correct answer is actually 4100.

4100, but I'm an engineer. I guess that's like cheating.
