Last night at dinner
Feb. 7th, 2012 07:01 amThe scene: Dinnertime
The backstory: Ana's learning her times tables
Me: Okaaaaaaaay... *drumroll* Ana! What is... SIX times SEVEN?
Ana: Wait. What? I didn't come here to learn! I came here to eat!
Me: Well, have I got a deal for you! Today's special! You can do both! TWO THINGS FOR THE PRICE OF ONE!
Ana: Seriously?
It worked out well enough, though. Ms. "I Came Here to Eat!" was able to get through her problems correctly, and she REALIZED something. IF it's something multiplied by ELEVEN, like... nine times eleven or five or something... it's going to ALWAYS be 99 or 55 or so on! WOW!
I acted suitably awed by this revelation, naturally :) Then I showed her the trick for two digit numbers and eleven, which isn't really a "trick" but meh. (Basically, since anything times eleven is OBVIOUSLY ten times one, you add a 0 onto your number and then add the original number, sans zero, to the new one.)
