Math-ew

Wow. So, Matthew was playing Mario bros and wanted to know if he had enough star coins to  open a new area... I showed him where it said he had 3 coins and then I showed him where it said he needed 5 coins.... He paused a second and then said "so I need 2 more coins?".  I know it's a basic thing, I was just terribly impressed... maybe 'cause I'm his mom... :)
