The courses being cut in Mathematics are graduate level courses which are not expected to be taught in high school. The likely reason is that there are few if any applicants for grad degrees. The subject matter can be very esoteric.
If I wanted to study higher mathematics, WVU wouldn’t be at the top of my list. Maybe MIT, Stanford, Chicago, CMU might be places to start looking.
Math profs cut likely to be few to none. Professors who teach grad classes do teach undergrad classes! There’s smoke and mirror savings in not having to give tuition waivers to grad students. Remember it’s not likely you have 200 math grad students! Mathematics graduate education is the least expensive of graduate STEM education.
Likely math was sacrificed so it didn’t look like they were only picking on the non-STEM fields.
