Maths as a subject embraces formulas and data. Without them, many problems remain unsolved. Just think about money exchanges, taxes, contracts, stocks, jobs, supplies, claims, discounts, tenders, wages, consumption, rates, measurements, times, etc. When this data is not available, or when it is incorrect or wrongly interpreted, chaos and confusion reign. Maths has been a companion and pillar of support for humans for thousands of years. The invention of Algebra in the 9th century by Muhammad ibn Musa al-Khwarizmi brought about a new era of enlightenment for engineering, analysis, measurements, and calculations. Hipparchus of Nicaea invented trigonometry in the 2nd century BC. It developed from calculating angles and distances, astronomy, mapmaking, surveying etc. While mathematics differs fundamentally from all other disciplines, it connects with all. Especially art and science.
