# Maths

Without maths, the kind of advanced engineering carried out at Rolls-Royce would simply be impossible. How else would we measure the complexities of engine performance, calculate the pressure on different components, or predict the amount of thrust we can generate for an aircraft?

The numbers we deal with are often huge, but anyone who has studied maths at school will recognise many of the principles we apply. For example, geometry and trigonometry are crucial for design, while probability and statistics help us constantly improve the way we manufacture our world-class technology.

### The maths of a Trent engine

“Maths can seem hard (even mind-boggling sometimes!), but once you get your head around it, it can become your everyday friend – and a great tool for tackling any problem. I like to think of a

Rolls-Royce engine as being like a big equation: we know what goes in one end and what comes out the other – but what happened in the middle?”

“I often realise that I’m using GCSE maths when I’m dealing with gas turbines – and I never thought those lessons would eventually help in my everyday job.”
