About the Course
In this course, Professor Keith Ball (University of Warwick) continues his exploration of solving equations, covering Topics A19 and A21 in the Pearson Edexcel GCSE (9-1) Mathematics (1MA1) Specification for Foundation Tier. In the first mini-lecture, we give an introduction to solving simultaneous equations by looking at graphs and thinking about what it means for two equations to hold ‘simultaneously.’ In the second mini-lecture, we show how to solve simultaneous linear equations by substitution (Topic A19) before moving onto solving simultaneous linear equations by cancellation in mini-lecture three (Topic A19). In the fourth and fifth mini-lectures, we look at how mathematical formulae appear in real-world applications and consider speed and distance, cost and rates, and Fahrenheit and Celsius, all of which involve linear or simultaneous equations (Topic A21).
About the Lecturer
Keith Ball is a Professor of Mathematics and the University of Warwick. His research interests are in functional analysis, high-dimensional and discrete geometry, and information theory. From 2010-14, Professor Ball served as the scientific director of the International Centre for Mathematical Sciences (ICMS) based in Edinburgh. He was elected as a Fellow of the Royal Society in 2013 and awarded the Whitehead Prize by the London Mathematical Society in 1992. Professor Ball is the author of Strange Curves, Counting Rabbits, and other Mathematical Explorations (2006), a recreational maths book aimed at those familiar with basic calculus.
