Let have a Test:

You need to make a calculation. Please do neither use a calculator nor a paper. Calculate everything “in your brain”.

Take 1000

So, You Got The RESULT!Β

Quicker you see the answer, sharper you are!

1. it’s nice….

2. You got me. i was so proud when i came up with 5000 in a flash.

• So now I know i’m not a genius…

• Ha ha! When counting by head, one can make these kind of mistakes. Ask any math frequent buddy, you’ll probably get the same answer. Key point of this test is the last step: Four thousands and Ninety plus Ten equals what? : Five Thousand π

3. I also first got with 5000 in an instant but when I understood my mistake, I figured out it as a awesome question.

Ha ha ha.. You too! –Gaurav

4. I got 4100 after reading it, but if I had heard it, I would’ve probably gotten 5000.
Why: I saw four 1000’s and a group of four other numbers that I knew added up to 100, so I thought 4*1000 + 100. If I had heard it, the numbers would have been added in order (incorrectly) and I wouldn’t have been able to do this weird visual thing I do with numbers.

this mean that you’re a genius! Congrats!—[Gaurav]

5. I got 3100….

You said take a thousand so I instantly thought to subtract a 1000 from zero to start off with making it -1000

Plus 40 makes it -960

Plus 1000 makes it 1040.

• -960 and plus 1000 makes only 40. so your answer should have been 2100. π

6. As always, You’ve a great sense of humor!

7. witty π
