Hi Mathematician,

$$(-3^2+4^2)+(\frac{3^2}{3})\\
=(\textcolor[rgb]{1,0,0}{-1}*3^2+4^2)+(\frac{3^2}{3})\\
=(\textcolor[rgb]{1,0,0}{-1}*9+16)+3\\
=-9+16+3\\
=10$$

There is a calculator on the home page. :)

Yes except you are best to keep g on the left and take 39 frm both sides.

equations must stay balanced.  Like old fashioned scales. :)

Yes he can happy.

- - = +

thanks Alan, I stand corrected.

What is that G?

Correct 0.005854 to 2 significant figures.

the first 2 significant figures are 5 and 8

the next one (5) is used for rounding.  it is big (5 or more is big) so the 8 goes up to 9.

the last 4 is of no consequence at all and should be ignored.

0.0059

Translated from Portuguese

as it does, in the log, the change of basis??

$$log_ba=\dfrac{log_{10}a}{log_{10} b}$$

Is that what you want.  It does not have to be base 10. It can be any base.  :)

É isso que você quer. Não tem de ser a base 10. Ele pode ser qualquer base.

Hi Dragontmaer :)

Why don't you get an accout here.  We would love you to join us and becoming a member is ultra easy :)

weight = mass * gravity

Hi everybody and thanks to Happy7 and the others who have given points for my wrap.  I appreciate it and i am glad that you find the wrap worth while.    

If anyone would like to recommend any threads for the wrap please let me know.  The most obvious way is to send me the address by private message.  These days the forum is very busy.  I do not read all the questions and answers.  I expect that I miss many good ones.  So please let me know if any draw your attention.  More people than just me would really appreciate it.   

It was very busy today.  I am very glad that so many people get in and help answer questions.  Today these people were Lanayia, haimaithproblems, BrittanyJ, Alan, CPhill, Heureka, Relic, Happy7, Tiddle, geno3141, Anonymous4338, Mathematician and SevenUp.  There were some good answers from anonymous people too.  Thank you for all these great answers.   

Now for some interesting posts:
