How many different ways can you find of fitting five hexagons together? How will you know you have found all the ways?

Abundant Numbers

Stage: 2 Challenge Level:

48 is called an abundant number because it is less than the sum of its factors (without itself). Can you find some more abundant numbers?

Baked Bean Cans
