Answer 2

Latin loanwords are particularly cool. modify ego - different self Quid professional quo - some thing for some thing Mea culpa - my personal fault Modus Operandi - frame of mind to operating once you've the want to make what you're putting forward look somewhat better subtle, throw in some Latin. and some adjustments from Spanish: Vamoose - from vamos, let's bypass Savvy - from saber, to attraction to close Booby - from bobo, stupid twister - from tornar, to tutor what's the determination one English loanword in German? Shitstorm - used in connection with the euro debt disaster..

Answer 3

I don't think posting here can solve the problem
I am interested in your problem and I would like to help
you can IM me xman0802003

the solution for the + * / - signs is very simple
Just sround each sing with spaces before your begin pasrsing

for example ((b+c)*2)
the could should be something like that

string a = "((b+c)*2)";
a.replace("("," ( ");
a.replace(")"," ) ");
a.replace("+"," + ");
a.replace("-"," - ");
a.replace("*"," * ");
a.replace("/"," / ");

now the string will be like that
( ( b + c ) * 2 )
now is it easier to prase?
