Hi anon,

Those x'es would be pronumerals which are unknown numbers :)

8.5x-4.3=3.3x+3.5

First add 4.3 to BOTH sides and tell me what you get :)

Then subtract 3.3x off both sides

If you need to, show me what you have done and I will help more:)

6" is 1/2 a foot.

so

(1/2)*(1/2)*10

Your question doesn't make sense.   

It is just  144 - - 401

Remember that - - makes a plus.

;)

(3.98-1.99)/1.99   then times it by 100 and put a percent sign.      

you can use the calc on the home page.  

Thanks Anon - you can head my fan club :))

To be honest I think geno answers more questions than anyone else and CPhill is not far behind.

Alan has also been a consistent answerer for a long time now and he can tackly the most advanced questions.

Heureka also writes many great answers and he uses Latex too.  Many other people also contribute as much as they can.

We all try really hard to answer everyone's questions.

It is great when people like you voice their appreciation.  

Why don't you join up properly.  It is very easy and there are a number of benefits :)

I think having your own personal watchlist is a really big benefit.

When you ask a  question it is automatically saved in your watchlist so it never needs to get lost.

Plus, you can search for your own posts using the search function.

You can also message people privately and make friends.  

Anyway - thank you :)

There is no answer - it is undefined.

You cannot divide by zero!

Hi Kimderano,

< and > are inequality signs.

When you use these you have inequalities NOT equations.  

use the calculator on the home page.

or

just move the decimal point over 24 places in  the direction that will make the number bigger.
