    For question 6, how come you knew to put 10 in the middle. The way I thought you needed to answer this is through just testing out each answer but obviously, the maths challenge is done through a quicker method.
    Could you maybe make a video on how to think about the maths challenge questions, would be very helpful

      So I knew the usual magic square when you're using the numbers 1-9 has 5 in the middle, because it's the middle number. Here as 10 was the middle factor, I used similar thinking - Also, 10 is the only factor without a 'pair' so the pairs of the other factors would need to go in the same row as it, 4 other pairs so you'd need 10 to go with each of the 4 pairs, and the only way is to put it in the centre
