Where can I learn stuff like matrix multiplication and other mathematical skills in excel?
Most of them you can find in the link: https://www.tutorialspoint.com/advanced_excel_functions/index.htm
Does anyone know if the latest Mac OS version of MS Excel is powerful, as in feature-rich, enough to run all of Jeremy’s spreadsheets? How about the online version of MS Excel?
Replying to my second part of the question: the online version seems quite limited e.g. running macros not supported as per https://support.office.com/en-us/article/differences-between-using-a-workbook-in-the-browser-and-in-excel-f0dc28ed-b85d-4e1d-be6d-5878005db3b6
