Looks good, 5 -1 mod 37 is 15, so 2 (5) -1 mod 37 is 30. Thank you! I’m wondering if my answer is correct. The extended Euclidean Algorithm is usually what I have trouble on. It is definitely true that 2 ⨯ 5 -1 ≡ 30 mod 37. I don’t usually see this written as “2/5”, but it makes sense: the number 30 ... theories of liability in pharamcy compounding
