Covering all the basics including fractions, equations, primes, squares and square roots, geometry and fractals, Dr Richard Elwes will lead you gently towards a greater understanding of this fascinating subject. Even apparently daunting concepts are explained simply, with the assistance of useful diagrams, and with a refreshing lack of jargon.

So whether you're an adult or a student, whether you like Sudoku but hate doing sums, or whether you've always been daunted by numbers at work, school or in everyday life, you won't find a better way of overcoming your nervousness about numbers and learning to enjoy making the most of mathematics.

Challenge 23


Write \(2017\) with the digit \(2\) with the operations addition, subtraction, multiplication, division, power of \(2\), power of \(3\), square root, cubic root and factorial. Parenthesis are allowed. You can use numbers with more than one digit, like \(22\), \(222\) and so on.



With \(11\) digits:

\(222 \times 2^3 + 222 + \frac{22}{2} + 2^3=2\,017\)

Can you do it with less digits?
