How do I add a pair of parentheses to each expression so that it come out to be True.

(a) 0 == 1 == 2

(b) 2 + 3 == 4 + 5 == 7

(c) 1 < -1 == 3 > 4

For each expression, how do I explain in what order the operators were evaluated

This is for my python computer science class. Thank you for your help.
