Knight’s Move Challenge

Knight’s Move challenges are quite popular. They can involve one more more knights and varying spaces that the knight has to traverse.

Our challenge is a simple Knight’s tour, where the knight should land on each square exactly one time to complete it. We are adding a way of keeping track that gets us to practise arithmetic.


Each time the knight moves from one number to another, it effectively performs an operation. This is what we call a simple function that turns one number into another number in arithmetic. On our grid, there are only so many operations that a knight’s move can create. These are mostly addition or subtraction operations. See if you can find all the possible addition and subtraction operations that can be made by a knight’s move on our 5 by 5 board.

Are there any knight’s moves that could be multiplication or division? What about raising to the power or squaring, can you find one or prove that it’s not possible?
