Choose starting ages below each cake. Think old !
Now trade candles between cakes and layers using the green arrows.


Ideas:  

* Set Math Cat's age to 100 or 200 or 300 and leave your age 0.
   Now click the right arrow on the lowest layer to move one candle.
* Choose any ages to start, then trade candles until both cakes
   have the same number.
