In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.

Hi MIF
It seems the plus problem is very persistent: http://www.mathisfunforum.com/viewtopic … 26#p253826

Re: plus signs in Latex
To speed up page loads, once latex is created it is kept in a large cache. If latex was always being created things would be really slow.
So if you write some latex that has already been done you get that old version.
Try changing it a little (say with a space or variable change) and it will likely have to make a new one that works properly.

Re: plus signs in Latex
So, the cache has the LaTeX version of that expression from before you fixed the plus problem?

Re: plus signs in Latex
Yes, and I can delete it manually, by looking up its cached name. Such as "f/f/29156445d5e534d194b44703db36ab1.gif" for the misbehaved image above.

Re: plus signs in Latex
LaTeX is not parsing the character ' at the moment. 
f(x) = x^2 :
f'(x) = 2x :

Re: plus signs in Latex
I see, so it’s \' rather than just ' now? Thanks.
