well i thought i should give julia a whirl since it got so much chatter 
around it , so i thought i could start of slow and simple and i run into a 
tree sort of ... so the problem is that i compared the results of two 
functions in an if statement with an and operator but it spiting some very 
basic error which i cant figure out what to do with ... so here is the code 
in question ..

________________________________________
a(i)=20*i - i^2
b(j)=50 *j - j^2
c(k)=40 *k - k^2
for i in 20:50
    for j in i:50
        if a(20)==b(50) and c(j)==a(k)
            print ("got it")
            break
        end
    end
end
__________________________________________

the error spit out is this ...

syntax: extra token "c" after end of expression
while loading In[11], in expression starting on line 6
i can figure that the roblem has to do something with comparing the outputs of 
functions using looping variables variable { c(j)==a(k) } ... but i dont 
understand why that should be a problem ... so either ways can some one give me 
the correct syntax or direct me to a specific DOC with 
the similar example ... thanks in advance .
