To solve the maze 100 problem we used a systematic approach. We started off by drawing all of the possible routes from the start to the end of the maze and colour coded them to make them clear. Then we added up the numbers along those route separately so we could find which one added up to 100. There was nine possible ways to get through the maze the 7th route we followed and added up equalled 100. From finding all of the routes and adding them up it was easy to find out the highest and lowest as we had all of the information ready.
