And then we find the third group. So we have 5 minus 6 squared, plus 6 minus 6 squared, plus 7 minus 6 squared. And what is this going to equal? So this is going to be equal to, up here it's going to be 1 plus 0 plus 1. So that's going to be equal to 2 plus, and this is going to be equal to 1 plus 1 plus 0, so another 2. Plus, this is going to be equal to 1 plus 0 plus 1. 7 minus 6 is 1, squared is 1.
