Journalism is a liberal arts major. I don't think anyone can learn math well. Mathematics in the postgraduate entrance examination subjects is not necessary for all university news. If the landlord wants to study mathematics or take an examination of mathematics major. I suggest you just take math classes in science and engineering or management. Mathematics in science and engineering is a little more difficult than economics and management. Mathematics in colleges and universities is generally divided into three parts: integral, linear algebra and probability. Many colleges and universities use Tongji version of the green cover mathematics textbook. However, there are also many schools of economics and management that publish their own books.
