  1. T-Total Maths

    Formula: T=5N+56 I tested that when: T-number= 47 T-total= 291 Below is a T-shape, and in each cell how number is connected with T-number on an 8 by 8 number grid. To prove the formula: T= N+N-8+N-15+N-16+N-17 T= 5N+56 How the formula works there are some example shown in below

  2. T-total Investigation

    (7 x 23) - (11 x 10) = 51 161 - 110 = 51 1 + 2 + 3 + 4 + 5 + 13 + 23 = 51 I found out that the formula for a 5by2 on a 10by10 grid is correct. I will now do the same on a 9by9 grid.

  1. T-Total Maths coursework

    I am going to do now is find out the relationships between the T-Total and the T-number using rotations of 270�Clockwise 9 by 9 grid size 9x9 Gird size 270� N = 12 5N = 5x12 = 60 G = 9 = 7x9 = 63 I now have enough data

  2. Maths Coursework T-Totals

    = x + x - 4 + x - 9 + x - 8 + x - 7 t = 5x - 28 This formula is the same as the 4x4 grid as it has a "magic number" of 28, identical to a 4x4 grid, we can predict that grid

  2. I am going to investigate how changing the number of tiles at the centre ...

    + 2 Then T = 2(5)( + 2(3)(5) + 3 T = 32 T = 83 If C = 5 and N = 5 Then T = 2(5)( + 2(5)(5) + 5 T = 105 These three checks are correct so I think my formula is working.
