Question 896717: how to find the sum of all the co-prime numbers less than 180

I'm sorry but:

Only a PAIR of integers can be said to be COPRIME TO EACH OTHER. Therefore the
way this problem is stated, it does not make sense, because no single integer can
be said to be a "coprime number".  It takes TWO integers to be CO-PRIME to each
other.  For example the pair of integers {8,9} are said to be coprime because
their only common factor is 1. What do you mean to ask about such coprime PAIRS
of integers?  What do you mean by the "sum of such pairs"?
