This question depends on your position, but in any case, it is impossible to become an outstanding entrepreneur without mathematics. Run a small business for a period of time, at least know how to calculate the cost, otherwise how to know whether to make a profit or lose? If you are a large-scale small company, then you should know the basic accounting operations. Besides, since you are Li Ka-shing, you obviously don't have to do quarterly and year-end accounting audits yourself. However, you should at least be able to understand the accounting statements sent by the finance department. If you are the president, you should take the advice of your subordinates. To put it bluntly, even if you hire some right-hand men and industry elites with high salaries, it must be Bole, otherwise. Will you trust a man who just makes up for what they have and let him squander your land? Ha ha.
