Copied! Given that tuples are sequences, You may use indices to retrieve precise things in the tuples. Take note that You may as well retrieve slices from the tuple that has a slicing operation.

Copied! This equation reads “a and b are congruent modulo n.” Which means a and b are equal in mod n as they've the exact same remainder when divided by n. In the above mentioned equation, n may be the modulus for both a and b. Using the values 17 and 5 from in advance of, the equation would seem like this:
