Economy can be divided into broad sense and narrow sense. Economy in a broad sense is an activity and relationship around the production, exchange, distribution and consumption of material materials needed by oneself and others for survival and development.

The narrow sense of economy should be commerce and management.

Whether in a broad sense or a narrow sense, whether mathematics is good or not does not play a decisive role.

If modern people do well in business, they can let people who are good at math work for them.
