Think silly to solve this funny math :)

There’s a charming little brain teaser that’s getting shared on everybody's Facebook wall..  It’s got various forms, but they all look something like this:

  • 2581=?

Here ya go…
The answer has to do with how many circles are in each number. So the number 8 has two circles in its shape(well..should say, count the eggs in each number..lol)  so it counts as two(eggs). And 0 is one big circle, so it counts as 1. So 2581=2. Ok, that’s cute, it’s an alternative mapping of values with implied addition.
