(But the sequence actually starts at 0)

Leonardo Pisano Bogollo, as well as being famous for the Fibonacci Sequence, helped spread Hindu-Arabic Numerals through Europe in place of Roman Numerals.

Excellent review, thank you!

A page to help clear up any confusions people may have about Scalars Vectors and Matrices.

Corrections, suggestions please!

I decided to add a section on the worn logarithm book, and found that Simon Newcomb actually discovered that!

See my revised version (use refresh): First Digits Rule

Thanks Guys!

Has anyone else seen I used for irrationals?

Good point, will amend.

Funny! But a good point, it would be nice to have one for BODMAS and BEDMAS.

A new page: Math vs Maths ... and more

Good page? Any mistakes? Do you have your own thoughts on this?

And any more examples for the second half would be appreciated.

Hi Bob,

Thanks for that, I will look into how I might be able to repeat the tabs in this version.

I think imgur (or the like) is the best solution for image hosting at the moment.

Every so often we get people asking lottery type questions, so I thought I would make a page to try to help them understand how chance works etc.

Here is my draft: The Lottery

I would value your feedback, any mistakes you may find, and any suggestions for inclusions.

Thanks bobby ... yes and yes: ±√(2x^2+c) − x is what I get now.

And another in the Diff Eq series: Homogeneous Differential Equations

The main weakness in this page is no explanation of why they are "Homogeneous". I played with linking **f(zx,zy) = z^n f(x,y)** to **dy/dx=F(x/y)** form but failed. If anyone knows a user-friendly way of explaining why "Homogeneous" that would be nice.

Comments, suggestions and error checking welcome.

Les is going to make some questions (with worked answers) for the bottom of the page.

Makes sense to me, I will put ±, thanks.

Have made changes to the page Separation of Variables

Is it looking better now? Did I miss any of your points in the rewrite?
