Yeah, they may not have but they are most likely written in a different way. Example: Is that   e ---- + 8 < 1 ----> (e/-4)+8 < 1 -4 or e ------- < 1 ? -----> e/(-4+8) < 1 -4 + 8 Miss Prophetess Posted at 11:04 am on Oct. 12, 2008 Quote: from asb at 11:44 am on Oct. 10, 2008 Quote: from hateitandloveit at 5:57 pm on Oct. 9, 2008 Quote: from HXC at 8:56 pm on Oct. 9, 2008 I CAME.    I SAW.    (and lol'd) I CONQUERED I assume you mean e/-4 + 8 < 1 rather than e/(-4+8) < 1 ... so take 8 from both sides e/-4 < -7 multiply both sides by -4 (remembering the inequality swaps when multiplying by a negative number) e > 28 et voila... Thanks... I remembered that when a fraction's in an equation, it must be multitplied.  But I didn't remember by what.  Now I know for sure it's the denominator.  I think I've got it now (hopefully, since the test is on Tuesday).
