We're gonna get 1 5th minus 5 3rds plus four. And now let us evaluate it at negative one. So minus, let's see, if this is negative one, we're gonna negative 1 5th, negative 1 5th, and this is gonna be plus 5 3rds, plus 5 3rds, and then this is going to be minus four, minus four. But then when you distribute the negative sign, this, so we're gonna distribute this over all of these terms. And so this is going to be, if we make this positive, this will be positive. This one will be negative, and then this one will be positive. So you have 1 5th plus 1 5th, which is going to be 2 5ths, that and that, and then minus 5 3rds, minus 5 3rds.
