(I've been away for a while. However, I'm back, and I have some new puzzles)
pause for groans Please can you give me a statement that is always true for digits 4 and 5, sometimes true for 6 and never true for any other digit. You may use a calculator, for once you know the statement, you will be able to prove that 1 plus 1 equals 4
If you put an infinite number of apes in front of an infinite number of computers, you get a pretty good idea of what internet chat rooms can be like

I know that you wrote that it isn't true for any other digits. Could it still be true sometimes for 9?

The number of segments in a calculator display for digits 4, 5, and 6 is 4, 5, and 6, respectively. This is true of no other digits, as this table shows:
digit  no. segments 1  2 2  5 3  5 4  4 5  5 6  6 7  4 8  7 9  6 0  6 Thus 1 (two segments) + 1 (two segments) = 4 segments Dale

Very good idea, Dale, so your statement would be...?
Also, I have never seen a calculator where 6 doesn't have 6 segments, but it could be plausable that such exist with only 5 segments making the statement sometimes true for 6. /Tomas

(I got it straight away  I like it when the clue is in the question!)
"The digits on a seven segment calculator display are made up of the same number of segments as the number they represent."

Hmmm...
Well, the above statement is false, full stop! A more accurate version of the phrase, in answer to the question, is: "This digit can be represented on a sevensegment calculator display, using a number of segments that is equal to the digit itself". But I am being slightly pedantic

... just being pedantic back.....!
That statement is ALWAYS true for 6!

You are right. So...
"When this digit is represented on a given sevensegment calculator display, the number of segments used is equal to the value of the digit itself".

Welcome back, Stephen!
I'm looking forward to your latest creations.

Thanks guys!
Yes, sounds like you have the right answer. It is sometimes true for 6 because there are a few calculators that display six without the "cap" on top: _ _ although most do look like this: _ _ _ I have another puzzle for you good people  I'll be back in a bit
