• Transum,
•
• Thanks very much for sharing your solutions. Have we found all possible solutions to this puzzle yet? Does anyone have an insight into a way to prove that we have found all possible solutions? What strategies did your pupils use to find the solutions they found?

We have found the following
ONE+ONE= TWO (143+143 = 286)by Francesca
FOUR + ONE = FIVE (5260+237=5497) by Jameel or (5370+321=5691) Ruby
EIGHT - FOUR = FOUR (15864-7932) by Jameel
TWO - ONE = ONE (864-432=432) by Natalie
TWO +TWO = FOUR (928+928) by Dorothy.

I had been tutoring the wonderful Betsy for five years. When the day came for our last ever session together before the end of her Year 13, I received this beautiful book as a gift of appreciation.

This a very readable book by Ben Orlin. I'm really enjoying the humour in the writing and the drawings are great.

Ben Orlin answers maths' three big questions: Why do I need to learn this? When am I ever going to use it? Why is it so hard? The answers come in various forms-cartoons, drawings, jokes, and the stories and insights of an empathetic teacher who believes that mathematics should belong to everyone.
