I probably wouldn't use Frames, they would give me too much trouble.
I do use CSS, it is a big help.

They must have cut out the background in a hurry. Does look like they used a pair of scissors.

True, it is easy enough to do that, and then in a years time I will have TWO email addresses that get spammed, hahaha. Oh, and I did think of Frames, but they can cause trouble in certain areas. They can make programming harder, and that is why most sites that use some php pages steer clear of them.

Just finding the best one!

The email address used to be shown on the site. There is software out there that spiders the web looking for email addresses to add to spammers lists, and this site has been around for 5 years, long enough to be on every spam list around 
But this forum is working very well. It is great that many people can be involved in the one discussion.
The only pain is deleting the "less-than-mature" people who like posting offensive stuff.

Oh, that's alright then. No ideas is no ideas.
When an idea DOES come along, be sure to post it here, and I will at least have a think about it.
BTW I'm not smart, just dedicated.

So, what are you saying, Rora, you don't think you have any good ideas? Hmm?
I have a list of things I want to do for the website, but I am open to suggestions. Email doesn't work, because I get over a hundred a day mostly spam, so the forum is the best place.
#6809 Re: Guestbook » How to learn Times Tabels » 2005-04-09 00:01:14
Indeed !
So, that calculator idea has bitten the dust. Darn
So nothing for it but practice practice .

Before you and Rora get too involved in "Duelling Avatars", I would like to give you both (and Insomniac, too!) a chance to influence this website.
If you need more worksheets, more puzzles, better Maths info pages, or any bright ideas as to how to make this place better, then let's start the discussions rollin'.
(Remember it was you, Zach, who prompted me to upgrade the style of this forum over Easter, and I will try to follow up any other good suggestions as time and resources allow)

OK, I won't ... and I had SUCH a cutting remark ready to go.
#6814 Re: Guestbook » How to learn Times Tabels » 2005-04-08 09:14:29
That might work ... hmmm ... I wonder if the teachers know about calculators when running the tests ?

A duck walks into the Library and says "Got Any Books?". The Librarian says "Yeah" and lends her a book.
An hour later the Duck brings the book back and says "Got Any Other Books?" The Librarian says "Yeah" and lends her another book.
This goes on all day until eventually the Librarian says "OK, that's enough, why are you always asking for books and then just bring them back an hour later?"
"Well", says the Duck, I keep taking them to Frog, and every time he just says "Read-It!".
#6817 Re: Puzzles and Games » Addition Problem » 2005-04-07 20:19:31
There's a point, How about:
16+24+53+7 = 100
16+24+57+3 = 100
17+24+53+6 = 100
etc ...

I recall using integer division in the past. It had special methods that may suit you.
Now if I could only find what I did with it ....
... I did find this: http://www.bearcave.com/software/divide.htm , the author has some C code that might do it for you.
The central part of his code has:
while (remainder < divisor) {
bit = (dividend & 0x80000000) >> 31;
remainder = (remainder << 1) | bit;
d = dividend;
dividend = dividend << 1;
num_bits--;
}
(he says that always goes one step too far, so he just backs up once.)
Is that what you were looking for?

A circus woman has two bars of gold, one in each hand. She is being chased by thugs who want to steal the gold from her. They are right behind her.
She reaches a wide ravine. A plank lies across the ravine. There is also a sign nearby which reads: 'DANGER. PLANK ONLY SUPPORTS TEN STONE.'
The thugs each weigh twelve stone; they can't cross. The woman weighs nine stone so she can cross but the bars of gold each weigh a stone each.
The woman gets across with the gold. But how does she do it?

Only temporarily, cherelle !
Read the information, do the exercises, and ask questions, you WILL get better if you work at it.
Let's start - pick something we can help you with - not your absolute hardest thing, but something you think you COULD be good at if you had a little help.
#6822 Re: Jokes » Bars? » 2005-04-05 17:45:37
Great stuff - everyone here laughed.
#6823 Re: Puzzles and Games » Addition Problem » 2005-04-05 13:24:11
Excellent ! Can't fault it. Must be right.

Doh ! That's just too good. Now you have revealed the secret of the ages, does the universe end soon?

So math DOES exist, then ... I though it was just a fantasy land.
