Mathematics and the professions

Mathematics is part of almost every profession. Check out the table below for the applications of mathematics in some of the most traditional professions.

Profession applications
Administration Administration requires a lot of planning, organization and control. Therefore, it is essential that the administrator has the ability to handle numbers. He will often have to prepare project budgets, plan and track research, and solve situations involving statistical calculations. The work of the administrator is directly linked to the accuracy of the numbers, so he must have mastery of mathematics to be successful.
Agronomy Calculation of chemical components for fertilization and sizing of areas to be cultivated.
Architecture Mathematics is fundamental for the architect to develop his work. The architect works in the construction of houses, buildings, renovations, restorations and in the planning of neighborhoods and cities. Architecture is a union of the areas of exact, human and art, as it requires multiple skills, such as mastery of calculations, intuitive designs and history.
Movie theater Many animations we see in the movies use mathematics through computer graphics. From the movement of characters to the background, they can be created by software that combines pixels into geometric shapes that are stored and manipulated. The software encodes information such as position, motion, color and texture of each pixel. For this, they use vectors, matrices and polygonal surface approximations to determine the characteristic of each pixel. A single frame of a computer-created movie has more than two million pixels, making it essential to use computers to perform all the necessary calculations.
Accounting The accounting professional performs many mathematical calculations, in payroll operations, labor calculations and determination of tax amounts, as well as to prepare the companies' trade balance.
Right The legal professional uses mathematics when working with causes involving calculations, such as goods, values, shares and inheritances.
Engineering Mathematics is essential to the training of engineers, whatever their field (civil engineering, electrical engineering, etc.). It is used in the construction of buildings, roads, tunnels, subways, railways, dams, ports, airports, power plants, telecommunications systems, creation of mechanical devices, development of machines, among others.
Geography Geographers use mathematics in various situations. There is even a branch called Mathematical Geography, which studies and analyzes the shape, motions, and dimensions of the earth. Mathematics is also used in topography for measuring distances and angles, and in cartography (map study) to make cartographic projections.
Geology The geologist uses several principles of mathematics to dig, know and evaluate the secrets of soil and stones.
Journalism Mathematics is useful to journalists in economics and politics, as well as those who use statistical data in their work.
veterinary Medicine

Mathematical modeling contributes to the therapeutic and surgical planning of various diseases, as well as helping to develop models for the dynamics of the cardiovascular and respiratory systems. Mathematics also assists in genetic research, such as probability theory, which allows one to discover the chances of obtaining a particular result from a cross. It is also very useful in analyzing the growth of virus and bacterial populations through exponential or logistic curves, determining the impact of epidemics or the growth of bacterial "cultures".


In meteorology, calculations help to understand the movements of the atmosphere. Meteorologists use mathematical and physical equations to interpret meteorological satellite and radar information, thus generating the famous weather forecasts. Mathematics is present in measuring wind speed, direction and distance. Numbers are also essential for measuring relative air humidity (expressed as a percentage), as well as recording sunstroke or sunlight duration in hours and tenths.

Music Music theorists often use mathematics to understand musical structure and communicate new ways of listening to music. They also use mathematics to understand musical scales, and some composers have incorporated the golden ratio and the Fibonacci number in their work. Read the article on Math and Music for more information.
Dentistry The dentist uses mathematics to calculate amalgam compositions, dosages, anesthetic doses and also to size prostheses and corrective devices.
Psychology The psychologist uses mathematics for statistical data analysis and test evaluation.
Tourism and Hospitality The Tourism and Hospitality areas work with tourists, so they need to make various currency conversion calculations. Statistical surveys are also important for finding out the number of tourists by country or state, or the number of people who have traveled in certain months. They also use many calculations with percentages, either to calculate discounts or to identify the percentage of hotel room occupancy. The same goes for food. For example, if the hotel has a 50% occupancy, only half of the food that would be purchased in case of full occupancy will be purchased, thus avoiding unnecessary expenses and food waste.
