hello I am trying to analyze this grammar: E -> T A . A -> + T A . A -> . T -> F B . B -> * F B . B -> . F -> ( E ) . F -> id . but I an getting error. the grammar is ok can you please help?

Symbols like + need to be quoted. So the grammar should be written like this:

E -> T A .
A -> "+" T A .
A -> .
T -> F B .
B -> "*" F B .
B -> .
F -> "(" E ")" .
F -> id .
