Explore and solve encrypted maths puzzles, in which numbers are replaced by letters or symbols, with this free online course.
This online course looks at three types of maths puzzle, their history and the puzzlists who created them:
- Cryptarithms: where digits have been replaced by letters, requiring verbal arithmetic to solve them.
- Symbologies: where numbers are represented by symbols, including examples from the ancient and modern worlds.
- Mathematical operator puzzles: where numbers are given, but the operator is missing. For example, what does the asterisk stand for in *1320=6?
You’ll exercise your brain, improve your problem-solving skills, and learn the art and science of deciphering maths puzzles.
