Math and Logic

Start in the Middle

In a circle puzzle like the ones below, dashed arrows mean to add and solid arrows mean to multiply. For example, the solution to the puzzle on the left is a number whose sum is 5+9,5 + 9, which is 14.14. The solution to the puzzle on the right is a number that, when multiplied by 6,6, gives us 12.12. By working backwards, we get a solution of 2.2.
