This is an example of a completed SetSquare grid. The aim of this puzzle is to insert the numbers 1 to
9 (once and only once) in to the grid, so that the calculations are all satisfied.

Note that these calculations are done in left-to-right order, and not in PEMDAS/BIDMAS order. If we look
at the calculation on the bottom row, we can see this in action, i.e. in left-to-right order this does
give us the result of 26, but applying PEMDAS/BIDMAS rules would give 21.

This is an example of a SetSquare starting grid - depending on the difficulty level, we can be given a
starting number. The best way to start a SetSquare puzzle is to look for calculations where there aren't
that many possibilities.

Looking at the calculation on the bottom row, we have (8+A)xB = 55. We know that the only
multiplications that give us 55 are 5x11 and 11x5. Cell B can't be 11 as this is not allowed by the
rules. This means that cell B must be 5, and 8+A must be 11, i.e. A must be 3.

If we look at the left column, we have A÷B+8 = 11, i.e. A÷B = 3. Again, there is a limited
number of ways we can satisfy this calculation,

- 9 ÷ 3 = 3
- 6 ÷ 2 = 3
- 3 ÷ 1 = 3

Looking at the top row, we have tha 6xAxB = 54. There is a limited number of ways we can satisfy this,

- 6x9x1 = 54
- 6x1x9 = 54
- 6x3x3 = 54

Looking at the middle column, we have (A+C)x3 = 39, i.e. A+C=13. Let's look at the different ways we can
do this,

- 4+9 = 13
- 5+8 = 13
- 6+7 = 13
- 7+6 = 13
- 8+5 = 13
- 9+4 = 13

Combining both of these means that cell A must 9, cell B must 1, and cell C must 4.

The only number we are now missing is 7, and that completes this SetSquare puzzle!
