  • There are actually only 5 solutions with all others being a permutation of the digits in the columns.
    Hundreds column can only be digits 125 or 134 (any arrangement)
    If 125 then tens column can only be 369, 378 or 648, with remaining digits in the units column.
    If 134 then tens column can only be 279 or 567 with remaining digits as units.
    These correct columns can be arranged in 6 different ways each giving 6x6x6=216 combinations x 5 solution sets = 1080 possible.

Math with Bad Drawings

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.
