Since the three lines starting with | are a continuation of the preceding line, they must be indented more. > mdcl :: [Int]-> [Int] > mdcl []=[] > mdcl l = mdcl ([mdc (tira(take 1 l)) (tira(take 1 (drop 1 l)))]++ drop 2 l) > > gcdl :: [Int] -> Int > gcdl l = tira l > > tira :: [Int] -> Int > tira []=0 > tira [x]=x Spelling out names like 'mdcl' and 'tira' will make it easier for us to help you. gcd isn't a problem because it is well established mathematical notation, but the others are opaque to me.
