Hello.
Let's say you have a 4x4 grid, you can make patterns by using any number of squares, connected or not. So, one pattern may use just one square, top left, another may use one top right, another may use the entire top row etc. How many patterns can you make from that 4x4 grid?
Cheers.

Hello.
OK, sorry, I'll try oto be more specific. We are using one colour.
One pattern could be:
XOOO
OOOO
OOOO
OOOO
another could be:
XXOO
OOOO
OOOO
OOOO
and yet another could be:
XOOO
XOOO
XOOO
XOOO
it's simply that a pattern could use one or all the squares, or any number in between, any orientation. Does that help?
Thanks.
