OMG I GOT MY MATH TEST BACK YESTERDAY
AND I WAS LIKE :O
I screwed up on this one question so dumbly (is that even a word?) that I just wanted to headdesk the... well, desk.
The questions was
-y^15
y^11
The rule is that if you divide powers, you subtract the exponents, right? The negative sign can go out because it's the same thing as multiplying (I almost said timesing) by -1. Therefore the answer should be -y^4, right? Because - y^15-11 = -y^4. So Ms. Choo, on her quizzes and tests, she always gives us the question, some place to work, and the answer line. I wrote -y^4 on the work space, and I dropped the negative sign in the answer!!! It was like, I GOT the right answer and I just copied it wrong!
And I was like
Such a stupid mistake... *facepalm facepalm facepalm*
