Highlight any 2x2 square within this grid.

Multiply the numbers in opposite corners.

Take the

Conclusion

Example

(54 x 45) - (44 x 55) = 2430 - 2420 = 10

Now try some other 2 x 2 squares within the grid

I've shown that there does seem to be a relationship between the stairs total and the position of the stair shape. However to certify that such a link exist, I will continue my investigating by using the same formula. Nonetheless, I will use different shaped grids i.e.

2. ## Staircase Coursework

So ad an example I will take steep 5, which gives me : n = 55. I now insert it into the formula: St = 6n + 44 Therefore: St: 6 x 55+44= 374 St: 55+56+57+65+66+75= 374 So by using the formula you end up with the same result like adding up the squares.

they all equal the same answer but the answer is higher. This means that it probably can use the same sort of formula. N N+1 N+2 N+10 N+11 N+12 N+20 N+21 N+22 I shall try to use the formula: (N+2)x(N+20)-N(N+22)= 40 (N2+20N+2N+40)-(N2+22N)= 40 N2+22N+40-N2-22N= 40 Therefore 40 = 40 Lorenzo
