Title: Math people help Post by: Njoutlaw88 on August 15, 2005, 12:45:26 PM I know this is a stupid question but what makes this negitive or postive? I know the answer is 10 over 3.
3(-2) -4 ------------- (-2 -1)(-1) Title: Re: Math people help Post by: Ida_Mann on August 15, 2005, 01:51:14 PM oh man, it's been a while.
is it something like a negative multiplied by a negative makes a positive? I don't know if I remember that right, but if I do that would make the answer -10 ------- 3 which doesn't make sense to me,,,,it's been a long time since high school. Id@ Title: Re: Math people help Post by: qt314nfla on August 15, 2005, 01:58:43 PM ida i've got the same answer as you do. and you have the right rational.
3*(-2)= -6; -6-4= -10 -2-1= -3; -3*-1= 3 answer -10/3 had the three been negative it would have had a positive answer for the reason ida stated above. hope this helps.

I know the answer is 10 over 3. 3(-2) -4 ------------- (-2 -1)(-1) Ok it's been awhile but if I remember correcty, you first start with the actions in parenthasis(sp?). So 3 x -2 = -6. -6-4 = -10. You sure it should be a positive 10? The bottom is right [-2 - 1= -3. -3 x -1 = 3. I come up with -10/3. -Mark Title: Re: Math people help Post by: Da_Mtg_Man on August 15, 2005, 02:01:57 PM Thats an easy one.
Just go to the back of the book and the answer will be there. ;D Title: Re: Math people help Post by: Mrs.Nightbreed on August 15, 2005, 05:35:00 PM I know this is a stupid question but what makes this negitive or postive? If top and bottom are the same it is positive. If one is positive and one is negative it is negative.

16/3 by the 5th power to the 4th dimension + -8=_______ solve this one. ??? Title: Re: Math people help Post by: mudmonkey on August 15, 2005, 08:56:09 PM the answer is simple. -10
_____ 3 i know this because i have algebra 1 in the eighth grade ::) . it is just like my old homework in the seventh grade(pre algebra*for those who arent good with math*) heres my work::: 3(-2)-4 ______ (-2-1)(-1) 3 times -2 is -6 minus four is negative 10 negative 2 minus 1 is negative 3 times negative 1 is positive 3 so the answer is -10 -------- 3 ~courtney~ Title: Re: Math people help Post by: qt314nfla on August 15, 2005, 08:56:40 PM call the math helpline or find it online. i'm done w/ math for today.

Title: Re: Math people help Post by: LakeMaryKid on August 16, 2005, 07:40:30 PM ahhh its negative because the numerator is negative, therefore the whole answer becomes negative.
