A few little mind benders and dilemmas for you: 1. Using only the number 5, a total of 5 times (using any maths equations) can you arrive at a total of 24? 2. The year 1978 has an unusual property. When you add the 19 to the 78, the total is the same as the middle two digits (97). What will be the next year to have this same property? 3. Using only two 2's and any combination of mathematical signs, symbols and functions can you make 5?
