I hate doing this, but I am desperate for sales, as currently a few hundred pounds short of being able to cover my bills this month.
Please, if you’ve ever thought about buying from me, now would be a great time. Even if all you can do is retweet this, I’d be so grateful (1/2)
@alisonkiddle # of columns is odd. Pair of cols 1-2, 3-4 etc. Each row in each pair has 1 blue, 1 white, so they balance. In the last column, there are an odd # of bricks. They pair off 1-2, 3-4, etc until you get to the last one, which has no partner and was by definition a corner brick 😊
@alisonkiddle If the corner bricks are all the same colour, then we have [odd x odd] = odd number of bricks and there is one more of the corner colour. Otherwise there are either [even x even] or [even x odd] bricks i.e. even overall and there are the same of each colour.
