Description

Explore fascinating maths puzzles

Discover maths puzzles, explore their history and practise problem-solving techniques.

You’ll explore: + Cryptarithms – puzzles where the digits have been replaced by letters. + Symbologies – puzzles where numbers are represented by symbols. + Mathematical operator puzzles – puzzles where the numbers are given, but the mathematical operator is missing (for example, what does the asterisk stand for in *1320=6?)

Through the course you will develop problem-solving skills, gain knowledge about the history, art and methodology of encrypted puzzles, and exercise your brain with fun challenges.

 

What topics will you cover?

  • Encoding maths puzzles, secret codes and symbologies
  • Solving and creating cryptarithms – puzzles where numbers in a mathematical expressions are encoded
  • Genres of cryptarithm including, ancient Hindu problems and alphametics
  • Special and unique cryptarithms, including prime numbers, logarithms, square roots and powers
  • Symbologies from ancient times to modern bar codes
  • The language of computers including, binary, ternary and gray codes
  • Decrypting ancient Egyptian number systems, Roman and Greek numerals
  • Barcode puzzles and how to solve them
  • Different types of operator puzzles including unary, binary and ternary
  • Modern operators including, logic operators, text operators and operators in Excel

It's a pity that in my school days there wasn't such a great teacher.

In this course I learnt many things which I have not learned before.

Interesting course.

Very nice course, and teacher is funny and to the point.
