On the bottom of page 29, in the second line of the proof,
you say "the second inequality", dont you mean the second equality?
Now, two lines below it, you say the "first inequality", which although similar to the first error, is infact a separate error,
deserving of a separate bonus point, right?
Actually, there are not two, but three errors. After the "first inequality" error, you say "as the third is very similar" - since "the third" is not specified as what type of thing it is(equality, inequality), it takes on the condition of being an inequality(as that was used earlier in the sentence with a order value(first)), and therefore is a separate error, deserving of a third bonus point, right?
