FRACTRAN

Fractran is a simple computer language. It is like a list of instructions that tells a computer what to do. The instructions are written using fractions. Each fraction tells the computer to do something with a number. For example, if the fraction is 2/3, the computer will take a number and multiply it by 2 and then divide it by 3. The computer will follow these instructions and it will keep doing this until it can't anymore. Fractran is used in mathematics and computer programming to solve complex problems.
