Hi there!
I'm using openoffice math to write a scientific method for school.
Now i've got a little problem. I used Math to create the following code:

Code: Select all

({log({81} over {80} ) } over { 11}  - {log({531441} over {524288} ) } over {12}  )  div   {log(2) }  over {1200} 


and as far as i can see it actually should return me this:

but what i get is this:
question_2.PNG

Any suggestions?

Thank you!
(I hope you understood this thread, since i'm german and doing rather hard with translating these math-expressions...)

Something better maybe:

Code: Select all

left ({log left(81 over 80 right) } over 11  - {log left(531441 over 524288 right) } over 12 right )  div   {{log(2) }  over 1200}
