Introduction

This is the School Code Breaking website, part of the intermathematics.com sites for international schools.

Maths and code breaking have a long and shared history. The skills that make good mathematicians, problem solving, logical thought and perseverance are the same skills that make great code breakers.

Governments and companies that deal in digital data are always on the look out for talented mathematicians – so who knows, maybe one day you could be a professional code maker or code breaker.

Hope you enjoy the challenge!
