The Prevalent Role of Mathematics in Daily Life

With an abundance of applications of the subject in the world around us, it’s only natural that the perception of the subject in today’s day and age has seen a significant change, where it is an area that keeps expanding and evolving, welcoming new concepts and methods.

⏰ Mathematics in Everyday Activities

In the past, mathematics was often considered abstract and disconnected from use. Fast forward to today, the viewpoint has changed to understand that maths is deeply connected to everyday experiences and solving real-world problems at workplaces, as seen in the following examples:

📌Budgeting and financial planning

Preliminary teachings of the subject, such as addition, subtraction and times tables, will come in handy with your shopping and budgeting. 
These skills can be used when comparing prices, computing discounts, or estimating your expenses when you are walking through the aisles of the supermarket.

📌Time management and scheduling

Application of divisions by breaking down 24 hours in a day into specific durations and tasks.
For example: 1 hour for breakfast, 2 hours for revision.
Calculating the duration to travel and the distance between the two locations for daily commutes to be on time.

📌Cooking
and measurements

Application of estimation, measurement and conversion when using different ingredients in the kitchen (cooking/baking).
Adjust the number of servings to the number of people based on the recipe.
For example: if 2 people require 400g of flour, 4 people need 400g x 2= 800g of flour.

🤔 Mathematics in Decision-Making

Proficiency in maths helps us make better, more informed decisions, ultimately enhancing our productivity and efficiency. As such, this skill becomes a valuable asset in the workplace across various roles and responsibilities.

Mathematics as the Backbone of Technological Innovation

Maths is a field of study that drives progress across some of the most innovative industries out there and is also used to solve some of the biggest issues in Science, Technology, Engineering, and Mathematics (STEM).

We will always have STEM with us. Some things will drop out of the public eye and go away, but there will always be science, engineering, and technology. And there will always, always be mathematics.

👩‍💻 Mathematics in Computer Science

This subject is very much the focal point when it comes to computer science and programming domains, where basic arithmetic operations like addition and multiplication lay the groundwork for computer functions.  These go on to make sense of some fundamental concepts such as:

  • Algorithm development
  • Data structures
  • Cryptography and cybersecurity

Algorithms

An algorithm is essentially a simple set of instructions to solve a problem. In computer science, an algorithm enables information to be put together in a structured manner to produce a desired result.
For instance, a Global Positioning System (GPS) with excellent algorithm development will lead Internet users to find the best travelling route based on different algorithms to check the traffic situation of the available travelling route options before deciding on the best route suggestion.

🚀 Mathematics in Engineering

Don't be surprised to learn how different engineers play active roles to fuel technology innovation through their mathematical knowledge and application, especially through daily calculations of maths operations and equations.

📌Civil
engineers

  • Maths concept: Structural analysis
  • Purpose: To evaluate whether a construction project design, (such as bridges and buildings) is safe to withstand conditions like wind and earthquakes

📌Electrical engineers

  • Maths concept: Algebraic equation, like Ohm's law V = IR
  • Purpose: Develop and design electrical circuits for the efficient wiring of an electronic device.

📌Mechanical engineers

  • Maths concept: Differential equations
  • Purpose: Predict various variables of things that are in motion, such as engines or machines, to have optimum speed and reliability.

Mathematics in Scientific Research and Discovery

It is only through understanding the different topics that make up the subject of mathematics that we begin to recognise its presence in the world around us. Hence, mathematics is also central to scientific research breakthroughs, helping us make sense of our natural surroundings and contributing to improvements in the quality of life and health.

🌍 Mathematical Modelling in Natural Sciences

Of course, we cannot miss out on the wide usage of mathematics to figure out the "mysteries" and solve real-life problems in the natural sciences. Mathematical models allow scientists to simulate real-world phenomena, such as climate change or the spread of disease. These models can help us understand the impact of different variables and predict how the system will behave in the future.

📌In the case of Biology, maths helps us to understand how life evolves with time through the concept of population dynamics.

📌 When it comes to Chemistry, maths enables us to study the relationship between how different items mix and change through the concept of reaction rates.

📌Finally, for Physics, maths guides us to find the reason why and how things move through the concept of motion and forces. Isn't that amazing?

💉 Mathematics in Medicine

The use of mathematics in medicine is pivotal, especially in terms of different branches like epidemiology, radiology, epidemiology, and medical genetics.
