5 ways maths is used in real life

From investigating crime to predicting extreme weather events, people across the world rely on maths to solve real problems.

1 Forensic Scientist

Just like the stars of TV’s CSI, forensic scientists solve crimes by analysing DNA samples, blood spatter patterns and much more.

The real life maths

Geometry and trigonometry is vital for blood pattern analysis; statistics and probability come to the fore when matching DNA patterns.

2 Cryptographer

From protecting military and financial data to chasing digital crooks, cryptographers write algorithms to mask information and unmask cyberterrorists.

The real life maths

Modular arithmetic helps create “digital padlocks” and keys; algebraic geometry is the basis of “elliptic curve” cryptography; abstract algebra protects classified information.

3 Foreign Exchange Trader

In seconds, you can decide how millions of dollars are spent. Foreign currency traders buy, sell and invest in currencies and use maths to quickly spot inefficiencies in the markets.

Statistics and probability help traders spot market gaps. Algebra, trigonometry and calculus let traders work out risk.

4 Nurse

Nurses are at the frontline of health care in hospitals, clinics and in the community.

The real life maths

Percentages, fractions, calculations and ratios are part of the daily work of nurses, who are constantly monitoring drug dosages based on factors such as a patient’s weight.

5 Meteorologist

Accurate and timely weather forecasts are critically important for emergency services delivery; preparation for extreme events; and safe aviation.

The real life maths

Probability and statistics assess weather; trigonometry helps predict location and movement.
