Math Is Fun Forum

Re-did the question, and yes, I got 72% too. Slight error in calculation.

Ouch... my mistake.

Are you sure 0.5 is the answer to 1698? I get sqrt(1-1.5) = sqrt(-0.5)

Again... shame no one answers these. Maths Is Fun homepage could have a link to these or something.

Whoa, I just realised that you have around 300 questions unanswered...

I'll try to answer these all but it might take some time.

Well, look at my threads. They're over two years old and right at the back.

If you really want to, I suppose the section could be organised a little differently. Perhaps the page numbers should be ordered alphabetically, not numerically. Or perhaps a drop-down list for users to select? Or maybe an implementation in the site itself to promote the use of your exercises.

Whatever you wish, just ask. I'm sure it wasn't Ganesh's intention to draw attention away from your work.

Welcome back.

There's a countdown numbers game downloadable free online somewhere... gotten some really tricky ones from that. I like to pick 6 numbers from the top, makes the arithmetic somewhat harder.
