mam tu pre vas taky mensi chytak, kto okrem luba zisti kde je chyba ? upozornujem ze to nie je o matematike ale o syntaxi jazyka :)

""
print (5*2)*3;
print "n";
print 5*(2*3);
print "n";
""

The functions described in this chapter may be used either with or without parentheses around their
arguments. (The syntax descriptions omit the parentheses.) If you use the parentheses, the simple (but
occasionally surprising) rule is this: if it looks like a function, it is a function, and precedence doesn't
matter. Otherwise it's a list operator or unary operator, and precedence does matter. And whitespace
between the function and its left parenthesis doesn't count--so you need to be careful sometimes:

print 1+2+3; # Prints 6.
print(1+2) + 3; # Prints 3.
print (1+2)+3; # Also prints 3!
print +(1+2)+3; # Prints 6.
print ((1+2)+3); # Prints 6.

Je to v jednej o'reilly-ovke vysvetlovane hned na zaciatku.

00000101000635400207639901655002021825620219232902192427

ok, tak pri vsetkej svojej neznalozti perlu predpokladam, ze funkcia ma () dobrovolne, cize pre prvy print ich vyhodnoti a preda parametre print a *3 v podstate zahodi a pri druhom preda cely vyraz

az teraz som si ro skusal spustat, predtym som nevedel ani o co go :]

a daj uz riesenie :]
