The Four Fours Puzzle
This is a well known puzzle: Express the numbers 1 to 20 using standard mathematical operations (add, subtract, multiply, divide) and exactly four fours. Remember BODMAS can make a difference to your answers. For example, 1 = (4 + 4) ÷ ( 4 + 4). In many cases there is more than one answer!
