8 is the same thing as 48 over 6. 32 over 3 is the same thing as 64 over 6, so minus 64 over 6. 4 is the same thing as 24 over 6. 1 half is the same thing as 3 over 6, so this is negative 3 over 6, the same thing as negative 1 half. 4 thirds is the same thing as 8 over 6, and then negative 1 is the same thing as negative 6 over 6. A little bit of arithmetic here, and let's see what we get. If we take 48 and we subtract 64 from 48, we get negative 16, is that right?
