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. |

[crash] can spell the names of all the Pokemon, other words he's still learning... |

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. |

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... |
|
| |
[krelnik], that would be dependent upon the base you use. |
|
| |
Log Bass10 x e = 2.71828183
Log Bass2 x e = 0.818284367 |

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. |
|
| |
"OK, who broke the TV with 238/0 ?" |
|

[Hits "twice the inverse of square root of pi times integral
over real numbers with respect to 'x' of exponential of
negative 'x' squared" button] |

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