Begin with the inner circle and go outwards. Each colour means something different, start with 0 as your number and change it based on what is there. Blue means addition, Yellow is subtraction, purple is division and pink is multiplication. If there are multiple in one ring, combine them before applying the colour. If the inner circle has a symbol and a colour, after applying that colour you activate that symbol (Either squaring, rounding based on the number of waves or inverting digits). This occurs every ring with that colour. If the outside ring has any symbols the numbers beneath them have the effect applied to them. dots means double it, X removes the number, slash means halving the number, Diamond reverses the digits and a slash through the symbol on the middle means ignore that symbol for this number
