My teenage DD just came wandering through them room staring at the floor with a scowl on her face so I started scowling back while raising and lowering my eyebrows. She noticed and cracked up and said "Oh I was just doing math in my head..." Ok then!!
Can you do mental-math?
I can manage more than I used to; but I do better if I see math written down or just use a good ol calculator. Teaching the kids helped a lot I think just with grading math fact sheets.
