Let me add a little bit here:
When using math formulas, one should know about the parsing rules form complex
expression
which do not have all the necessary parenthesis.
Different systems do have different parings rules.
In the case of a^b^c, the expression is ambiguus because

and gnumeric have a problem with the correct order of operations when dealing
with exponents. The gnumeric result is very strange.
This problem has probably been reported before but just in case it has not, it
