May 18, 200422 yr okay, this might sound silly, but has anyone ever understand why when you multiply a negative number with another negative, you get a positive number? I just try to get an example or imagine something that would prove me that, but I can't get it..... it's like fine, I follow the rule but I can't understand why it does that! The other one is for example -7--7 ends up being zero, but that one I get it by, I suppose, thinking it is the say as "no, he's not not here" (or something like that, that means yes)
May 18, 200422 yr Math is definitely NOT my strong point :anxious: I passed it by a hair in high school.
May 18, 200422 yr Math is definitely NOT my strong point I passed it by a hair in high school. me too! and that's only b/c i talked to my teacher and begged her to let me pass. :lol:
May 18, 200422 yr Yeah, get this! At the end of first semester in grade 12 I asked my math teacher if I was going to pass the course so I would know if I had to apply to re-take it next semester, and he told me I was gonna pass. But it turned out he looked at the wrong mark and I actually got a 45!! So he bumped me up to a 50 because it was his mistake...:anxious: whew.

The other one is for example -7--7 ends up being zero, but that one I get it by, I suppose, thinking it is the say as "no, he's not not here" (or something like that, that means yes) For the subraction, imagine it on a number line. You're at -7, and you want to subtract another -7. If you were just subtracting 7, you'd move "left" on the number line to -14, but since you're subtracting a negative number, you move the opposite direction, back to 0. The same principle applies to the multiplication. I may sound like I'm talking to a baby, but I actually had to explain this to another college-age person a few weeks ago. :stunned: Also, the double-negative thing works too. :P
May 18, 200422 yr I failed math twice in high school. Never took it again after that, except for a statistics class I had to take in university.

May 18, 200422 yr I'm taking my one required math course right now, and hoping to barely squeeze by with a passing grade so I never have to take math again. :lol: I really wish I'd taken it last year when it might have been a little fresher on my mind from high school. :rolleyes:
May 18, 200422 yr Yes, you were. My grade 11 math teacher knew how terrible i was in math, he bet me $20.00 that i'd fail the exam. :lol:
May 18, 200422 yr I know..hahahaha I was determined to pass so i stayed up and studied all night....all the wrong things...and i failed. :lol: BUT the teacher retired so i never saw him again. :lol:

May 18, 200422 yr MATH IS EVIL. ARGH. I have my finals coming up on Monday :rolleyes: I feel sick all of a sudden.
