Mental arithmetic improving remote control   (+14, -1)  [vote for, against]
Let kids learn as they surf tv channels

A remote control, but with a '+' and '-' key on it, so when selecting channel 453 and you're currently on channel 189, you type '+' 264. Obviously with an override, so I don't have to use it in maths mode.

Limited to add and subtract. Don't think it needs Sin, Ln, Log, cube-root etc.

You'd probably want to couple this with a randomisation of assigned channel number, so as to avoid kids performing over and over again the same additions and subtractions between their few favourite channels.

oh very good! my kids learned to read from the TV guides.

Bun for bringing back a happy memory of my then 2 year-old son spending a puzzled few minutes pointing my calculator towards the TV.

Actually, I think the repetition is useful. Then if she someday needs to subtract 36 - 29, she can remember "Ah, 36-28 = Seinfeld, so 36-29 must be seven".

surely we should have multiplication, division, squareroot and square. Need channel 16? 4square.

I can see this becoming a bit like Carol Vorderman on Countdown*. If the remote was just armed with numbers 0-9 and a range of mathematical functions, the challenge will be to get to the right channel number in double-quick time. Splendid.

*Countdown. Daytime TV quiz. Containing mathematical competition section.

For kids? Heck, I need this for myself!

I couldn't help but think of a cable channel in the US called "e" and wonder how you would get there from an integral channel number.

(Actually its called "E!" but humor me).

Let's see, volume 2 raised to the power of 10...

Very good!

You're scaring me. I still haven't got over the Particle Physics category on Jeopardy yesterday.

//Actually its called "E!"//
So you'll need a factorial button as well.

e! = Gamma(e+1) = 4.26082

Wow, a halfbakery full of mathmaticians. I'm spooked.

9i+15, for the imaginary channel.

2 + 0 = 2

I'd have to cheat off other people's remotes.
