Engineering is a derivative of the ancient School of Architecutre. I have a degree as a Master of one field of study granted by the University of Virginia Graduate School of Archicture. I also have an AB (not a BA since it's written in Latin) in another highly complex field.
My first major (quickly shed) was as a Math Major working on an AB in Math.
So, what was it you were saying about Liberal Arts Degrees?
There are two paths to a math degree - BA and BS. The BA is much easier and intended for things like teaching, where one only needs to know high school math.
The BS degrees math are the ones people can get real jobs with.
