$44 seems an awful lot for one pack of cigarettes.  Are they rolled in gold leaf?

What rate of interest do you want?

Thanks Alan.  

There are 3 numbers after  the point so there must be 3 zeros on the bottom of the fraction.

$$0.125=\frac{125}{1000}$$

Hi Edison,

Welcome to web2.0calc forum.  We hope that you like it here!

Thanks for answering this question too.

Your name will appear in today's 'End of Day Wrap'.  Take a look.  It is how I communicate with everyone on the forum.  Some days I don't have much to say but other days I have a lot of information to pass along.  

Melody.

well, the only prime factors of 33 x 5 are 3,5,11

none of these is a factor of 32 or 52 so the Highest Common Factor is 1

I'll take your word for it MacGamer04 

I think that you should talk to your school councillor.

Hi Bertie,

Thanks for checking BrainChap's answer (and for advertising this fact).  I don't always check answers but I know that they should be checked and this makes my role much easier to execute well. You could also have given BrainChap a thumbs up.  He would have liked that! 

Oh! thanks for the humour too 

Hi alanb1291,

Welcome to Web2.0calc forum.  we hope you like it here.

Thanks for that answer.  i just want  to clarify a couple of things.

 "Log10 of 100 is 2".  

This is worded log of 100 base 10 is 2   It is written   $$log_{10}100=2$$

This is true because $$10^2=100$$

----------------------------------------------------------------------------
I have writen this in Latex - using the latex tab in the ribbon above 

$$log_{10}100=2$$    is written in as log_{2}100=2

and

$$10^2=100$$    is written in as 10^2=100

Why don't you have a play with it!

You can also get subscripts and superscripts to display via the drop down format keys in the top line.

does that make sense?

I wrote some excellent notes for this but the thread will not display in the new forum. Drats!!!!

Anyway, here is a site that might help.
