Then you have 4 times 8, which is 32 over 3, so minus 32 over 3 plus 4. Then you have minus 1 half, we're just distributing the negative, plus 4 thirds, plus 4 thirds, and then you have minus 1. Now we just have to add up a bunch of fractions to simplify this thing. What do we get? This is going to be equal to pi times, see our least common multiple looks like 6. We're going to put everything over a denominator of 6. 8 is the same thing as 48 over 6.
