Math Brain Teaser

Note: This must be done in your head only. Do NOT use paper and pencil or a calculator. Also, do it in the order that it is written.

 

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?

...dam...how did I get that WRONG??? :D

 

*grabs a pencil and paper*

 

huh...

 

Ah...added to the thousands place instead of hundreds on that last 10...wow, that's kinda sad. :D

 

I'm sure that was the point of the problem. On paper you wouldn't make that mistake nearly as easily as in your head.

Since the base wasn't specified try doing it mentally in base 5 for an extra challenge. :D The answer could be [math]1200_5[/math].

 

BTW, tried hiding this answer but I found the hide tags don't work with the math tags.
