The entire figure of the Numberss on the interior of the T-shape is called the T-total

The t-total for this T-shape is:

1+2+3+11+20=37

So 37 = T-total

The figure at the underside is the T-number, So the T-number for this form is 20

Purposes:

1 ) Investigate the relationship between the T-total and the T-number

2 ) Use the grids of different sizes. Translate the T-shape to different places. Investigate relationships between the T-total and the T-number and the grid size.

3 ) Use grids of different sizes once more, seek other transmutations and combinations of transmutations. Investigate relationships between the T-total and the T-number and the grid size and the transmutations.

Aim 1- the solution

T69= 50+51+52+60+69

=282

T22=3+4+5+13+22

=47

In the diagram below it shows the difference between the T-number and the other Numberss. First is the T-shape in inquiry:

123

11

20

This is the T-shape and here is the Difference T-shape:

N-19N-18N-17

N-9

Nitrogen

This shows the difference N= T-number

In the T on the old page I have noticed that the first difference from N is 9 which is besides the Width of the square.

I? ll put that thought into another T. Note W= width figure ( 9 )

N- ( 2W-1 ) N-2WN- ( 2W+1 )

N-W

Nitrogen

This is the same thing as earlier but shown algebraically.

The expression for the Value of the T-total now is shown as:

5N-7W=T-total

Aim 2- different sizes and relationship

I know this works for the grid 9 by 9 but I? m non certain if it? ll work for any other grids.

Here is a trial for a 10 by 10 grid

T22=1+2+3+12+22

=42 I notice this is 5 more than 9 by 9

T69=48+49+50+59+69

=275Obviously no form

at that place.

Method trial?

( 695 ) -70=275 YES it worked

My method seems to hold worked out as it is logical and reasonably directly frontward to explicate.

As there are 10 in each row it? s obvious that the row above will be 10 less than the row below. So 68 is 10 less than the T-number 78. If you calculate the whole T you realise that row 2 is 10 less than row 1 and row 3 is 20 less than row 1, but there are three relevant Numberss in row 3 which are 19 less and 21 less than the T-number. These cancel out to organize 20 each, So eventually we get ( 110 ) + ( 610 ) = ( 710 )

=70

Or =7W

Aim3- Transformations stretches and there effects on the expression

I? ll do this with a 12 by 12 foremost, as this will give me adequate truth to get down with.

Stretch A will be called ST64 as it starts at 64, it? s a stretch of 2 in both waies.

St64=26+27+28+29+30+40+52+64

=296

I think I can work out the expression utilizing my old method so:

12+24+36+ ( 436 ) =216

21612=18

This means the expression is:

8N-18W=T-total

8N= figure of whole numbers in the T-shape

18W=difference figure calculated

Decision:

The size of the T-shape calculates the figure before N in the expression and the grid size calculates the value of W. the figure before W is calculated by looking at the rows and happening how many rows off from the T-number they are. If the T is regular so the W figure is negative but if the T is flipped upside down the W figure is positive. Written by
