## 'A-magical Number Maze' printed from http://nrich.maths.org/

The rows, columns and main diagonals of a $1$ - $9$ magic square
add to the same number, $15$.

This magic square has had doors, with operations written in
them, opened to make it into a maze.

Start wherever you like and go through every cell using all the
numbers, doing the operation indicated to the numbers, and go out
through the exit marked in cell $8$ with a total of $15$!

You must use the operations and numbers strictly in the order
you meet them. For example, if you try starting at $4$ and go
across the top row you must do it like this:

$4\times 9 = 36$

$36 - 2 = 34$

NOT like this:

$4 \times (9 -2) = 4 \times 7 =28$
