What surprises me is all of the Spring Chickens here who have a low score to

I did pretty well but this one has me stumped. Why is it possible to get two different answers using the same numbers?

THIRD QUESTION:
VERY TRICKY ARITHMETIC
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?

SCROLL DOWN FOR THE CORRECT ANSWER.....
~~~~~~~~~~ ~~~~~~~~~~

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?

I kept trying to figure this one out too. THEN I Googled it. Here is what I was doing wrong. I was adding 100 instead of 10 at the end. Must be a common error.

Okay, I can see it now. I was adding 10 to 4090 and getting 5000 instead of 4100. I got the same wrong answer at least five times when I was trying to solve the problem. Duh. It seems so obvious now that you've given me the clue! Thanks happylabs!
