Question 6

Σιγά, μια αλλαγή σε παράνθεση θα αλλάξει το αποτέλεσμα;

Δηλαδή η παράσταση 3 + 2 ** 2 - 2 + 3 / (3.0 +3)  είναι διαφορετική με την (3 + 2) ** 2 - 2 + 3 / (3.0 +3) και την 3 + 2**2 - 2 + 3 / 3.0 +3 ;

Score: 3 of 3

5.53 + 2 ** 2 - 2 + 3 / (3.0 +3)15.5
23.5(3 + 2) ** 2 - 2 + 3 / (3.0 +3)123.5
93 + 2**2 - 2 + 3 / 3.0 +319

Είδες, μια παρένθεση επηρεάζει το αποτέλεσμα, μπορεί όμως να τύχει να μη συμβεί κάτι τέτοιο! χμμμ...
