You do no one a favor, particularly not yourself, when you:
1) Fail to learn better notation, particularly since it was only from yesterday.
2) Post the same problem without comment.
We did this problem yesterday. You were instructed on how to use parentheses to the benefit of all. Try this:
1) What was it about the previous response that you found unsatisfactory?
2) Can you PLEASE add, at least, additional parentheses to clarify meaning.
2/1/10 in it's strictest interpretation would be (2/1)/10 = 2/10 = 1/5.
You may mean (2/(1/10)) = 2*(10) = 20.
It's possible you mean 2 + 1/10 and you just invented new notation for mixed fractions.
Perhaps, again with the new notation, you mean the tenth root of 2.
So, what is it, what have you done, and what would you like us to do for you?
