Rubik's Cube: Have you solved it?

  I used to be able to do the regular Rubik's cube in about 5-6 minutes but that was back in the eighties. I do have a cube at home which I did a few years ago but it took me days.

  I didn't think you could dis-assemble them without removing some of the stickers since they hide the screws that hold it together?

  I find algebra to be very different to doing mental arithmetic, algebra and trigonometry I find much easier than mental arithmetic.

  Palmtree,

  Algebra is pretty straightforward if you have a good teacher. Most people use algebra without realising that they use it.

  For example if you have a bill for three items that comes to £2.50 and one item was £1.30 what was the price of the other two identically priced items?

  No problem I can solve them within 20 minute at the least.

  Jus think logical and practice a few days, then you get to find out the tricks

  Wrong.

  There is nothing more frustrating than trying to solve a cube that has exploded and someone has put it back together with a piece the wrong way around.

  It's ok for those of us that recognise that it can't be done and can fix it, but for a beginner it is a shortcut to insanity.

  If you turn one layer 45 degrees you can pop the middle cube of a side out. This allows you to correct whatever is wrong and make the cube do-able again.

  If the cube starts getting stiff, candle wax is a great lubricant.

  Have fun
