Our big problem of the week this week is the border problem. We where given a 10x10 square like the one below, we had to work out how many red squares there are without counting them all individually.
My strategy to work it out was to take a side length or row and ignore the corners for now. Times the number of squares in the side length without the corners by 4 then add the corners back onto that number to get your answer.
r-c=s sx4+c=a
