Yeah this is really weird. The author knows one "mathematical" measure, 'expected value', and calls that "mathematics". Ignoring the fact that mathematics have given us way more measures such as variance and the other moments that are just as important and "mathematical". Then microeconomics have given us 'utility' etc. Finding one mathematical concept and saying "mathematics say this" is so strange.
