Math Is Fun Forum

Thanks Calligar. Questioning is an important part of mathematics.

Yes, this gets me every time, too. It is just so natural to simplify, how can it be wrong?

It remind me of the 2=1 proof:

Let a=b
a² = ab
a²-b² = ab-b²
(a-b)(a+b) = b(a-b)
a+b=b
1+1=1
2=1

The error is when we simplify by dividing by (a-b)=0

Be that as it may, I can choose a less controversial example.

I "un-buttoned" it ... because it misbehaved for me.

The LCM calculator is a Flash App that uses my "full precision" library

But the GCF calculator is a fairly simple javascript program ... I could re-make it in Flash.

Thanks noelevans, well argued and well said.

Thanks guys

I edited a file or two in some special way. Can't remember which or how. Hopefully some research will help.

New version (0.6): Least Common Multiple Calculator

I upgraded it to use my "Full Precision" functions, so it can handle larger numbers, so lots of changes to internal calcs.

Again, could you throw some numbers at it?

If I can figure out how to do it!

Thanks anonimnystefy!

Calligar: your opinion is not too late (I will continue listening to feedback) and is very interesting, thank you.

Just for fun (ignoring the million dollar fees!), who would you like as a presenter? What about Morgan Freeman, Sean Connery, Seth Green (he does Chris Griffin on Family Guy) or anyone else?

Thanks noelevans, both for the thoughtful feedback and the nice words.

It seems that "S" and "E" are both preferred. At this stage I will be getting the people who made the "S" video to make more, but modified according to feedback.

So far I have:
* Animations are good, but should not be distracting like the "V" video
* Slow down a little (probably simplest to add a few seconds pause after a key point, or calculation)
* For me I like having music, but perhaps at a lower volume.
* Presenter should have a clearer voice (necessarily female?)
* E has the best number line
* E has the best three-number explanation

Well, that is some good encouragement!
