Why do I need maths after my GCSEs?


Trigonometry, Pythagoras’ Theorem and Geometry – are you really going to use this when you leave school? You’d be surprised…

Learning maths is much more than answering tricky questions in strangely named topics. It teaches you how to problem solve, will help you manage your money and will definitely support your career, whatever it may be. Still not convinced? We have a few examples for you.

Job role Why maths is important
Army officer To join the army, you will need a GCSE in maths. You will also need analytic and problem-solving skills to pass the BARB test on entry – these are skills that are most associated with maths. Then, once you’re in, maths will help with problem solving, teamwork, using new technology, understanding defence systems and loads more.
Business Owner Business owners use maths in their accounting, as well as their inventory management, sales forecasting and financial analysis.
Chef Maths is important when you are a chef as you will need to convert weight, work out measurements, follow recipes and even use maths when tweaking your finished product. And, you’ll want to cost your meals in a way that will make you a profit!
Construction Maths doesn’t just help with measurements and building, the Pythagoras’ Theorem is so important when designing and building structures, especially roofs. And, it’s important when quoting for jobs, estimating material quantities and more.
Doctor As well as needing maths qualifications, doctors will use maths when administering drugs, calculate weight and measurements quickly in their head, understand X-Rays and much more.
Electrician Electricians use maths including addition, subtraction, multiplication, and division, to perform routine measurements and calculations at work. They will also use fractions, percentages, and decimals to figure out things like room dimensions, wiring lengths, convert watts to kilowatts, and calculate loads.
Firefighter You will need a maths GCSE to become a firefighter and you’ll take a numerical test during the application stage to prove you have an appropriate knowledge of maths. Once on the job, maths will help with calculating pump pressure to determine the PSI, knowing how much water is needed to put out a fire and more.
Geologist As a geologist, you will use trigonometry to correct distortions in satellite imaging for maps and calculate bedrock layer dips, understand angles and gradients for topography and work out infiltration rates and soil mechanic calculations. 
Hairdresser Much like a business owner, a hairdresser will use maths in everyday life to help run a salon – planning your time, stock management and ordering supplies, just to name a few. You will also use maths when taking payments, giving colour treatments, sectioning hair and interpreting numbers.
Marketing Maths is a key part of marketing. As well as using maths in everyday office life, it will help you spot trends and patterns in behaviour, understand analytics and data, and help with reporting and budgeting.
Midwife Not only do you need maths to administer medication and convert weight into different units, but you’ll need to calculate how much food each baby needs and how often they need it based on their weight and other factors.
Nurse You’ll need a Maths GCSE to be able to start your degree in nursing and there will be a maths test each year during your studies. This will make sure that you can carefully and correctly administer drugs, IV drips, take and understand observations and more. 
Pilot Geometry will help you plan your routes to fly and keep your aircraft on course. You’ll also need to read directional compasses, calculate how many degrees to turn your aircraft during flight and understand how the angle of the aircraft will help you avoid a hazard (like a storm).
Plumber Maths (particularly algebra and geometry) is vital to deal with water pressure running through pipes, estimating costs of work, reading blueprints, understanding layouts, planning your work and creating diagrams.
Police officer To join the Police, you might need a maths GCSE or need to sit a calculation test as part of your interview. Once you are a Police Officer, maths will be everywhere! For example, for investigating traffic accidents you will take measurements and calculate angles to help with evidence.
Retail shop assistant Aside from the obvious working out the correct change and handling money, you will need to know how to add discounts, calculate offers, monitor and balance stock.
Sportsperson Maths is becoming more and more important in sport. From measuring and analysing performance statistics to creating a nutrition plan, maths is everywhere. Technology can definitely help, but you need to understand how to interpret and monitor the data.
Teacher You don’t just need maths if you are a maths teacher. 

As a teacher, you’ll use maths to help with marking, lesson planning, time management, predicting grades and much more.

Hopefully, this has helped you understand that no matter what career you want to pursue, maths will always pop up. There are thousands more that we haven’t even touched on here, but we can assure you, we will find the maths in everything! And, maths isn’t just important in your career, you’ll use it in everyday life as well (but that’s a story for another day).
