Well, I'm not Mathman and I'm not a programmer, but I do have an engineering degree, and did get a math minor, and I came up with 1. Eight in the numerator over 2 times 4 in the denominator is how I took it. It is ambiguous.
Edited to add, I'm also almost 60 years old and school was a long time ago.
