Mathematics in finance is just a tool, not very important, the key depends on your understanding. The so-called math difference is a very vague concept, such as the province where your basic education is located. If you are from Shandong, Henan and Hubei and want to go to Shanghai for finance and economics, don't study badly. If it is a province with developed education money in the west, I suggest you reconsider. I hope it will be adopted. Thank you.
