NO, I'm not askingyouthis like I dont know it, it was a question on a website. However this question only works when spoken, so I guess it backfired. Sorry!
Here is the question on the website found:
"Very tricky arithmetic! 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?
Did you get 5000?
The correct answer is actually 4100.
If you don't believe it, check it with a calculator! Today is definitely not your day, is it? Maybe you'll get the last question right.......Maybe."
