Maths T-Totals

Look at this t-shape drawn on
This 9 by 9 grid.

The total of the numbers inside
The t-shape is 1+2+3+11+20=37.

This is called the T-total.

The number at the bottom of the
T-shape is called the T-number.

The T-number for this T-shape is
20, the T-total for this T-shape
Is 37.








Part 1

In this part of my investigation I am going to investigate the relationship between the T-total and the T-number on this 9 by 9 grid.
