@Warren H the second one

2018-01-29 03:07:16 UTC

the negative sign stays with the number it is attached to

2018-01-29 03:10:14 UTC

Okay. So I got 3/7 the first time. But it's actually negative 3/14ths? Or -3 over 14?

2018-01-29 03:11:53 UTC

Yep. If you're asking if there is a difference between " negative 3/14ths vs -3 over 14" the answer is no, they have the same value

2018-01-29 03:12:39 UTC

Uh. Divide both sides by 9

2018-01-29 03:12:48 UTC

Oh geez

2018-01-29 03:12:55 UTC

I didn't see all this

2018-01-29 03:13:16 UTC

@Warren H One thing you might notice at the beginning: think about the equation -4w = 6/7

2018-01-29 03:13:39 UTC

one things you might notice is that the left side is -4 * w, and the left side is a positive number (specifically 6/7)

2018-01-29 03:13:55 UTC

that means w times a negative number is something positive

2018-01-29 03:14:41 UTC

so whatever w is, w must be some negative number, since -4 times a positive number would be negative.

2018-01-29 03:15:34 UTC

@Warren H This ^ might help as a kind of double check on your work, thinking what sign the final answer should have

2018-01-29 03:16:18 UTC

Okay yeah that makes sense.

2018-01-29 03:16:32 UTC

Ive been working a lot with linear equations

2018-01-29 03:18:57 UTC

@Warren H Yeah they are an important building block for a lot of things but there can be a lot to keep track of when getting used to them. Any thoughts in particular about linear equations? Let us know if you have any questions in the future!

2018-01-29 03:22:31 UTC

Haha I don't like them lol. The worst part of math for me is fractions, and finding missing numbers like x lol

2018-01-29 03:24:41 UTC

@Warren H haha yeah if you remember up there ^^^ the first way I wanted to solve for u... first thing I did was cross-multiplied the denominators because I don't like using fractions either if I don't have to.
Are you doing this for a math major?

2018-01-29 03:25:41 UTC

Yeah I will try to remember that

2018-01-29 03:26:14 UTC

And nope not at all. I'm majoring in media production. This is just a required core class. Even tho I took 4 years of math in high school ðŸ™ƒ

2018-01-29 03:28:27 UTC

@Warren H yep it's a common core req for almost everybody. welp, feel free to ping <@&387091385075105804> for help here throughout the semester!

2018-01-29 03:29:02 UTC

What's AE?

2018-01-29 03:29:13 UTC
2018-01-29 03:30:18 UTC

@Warren H Academic Expert, it pings everyone has volunteered to make themselves available to anyone asking questions. Lots of fellow students and teachers and former teachers here

2018-01-29 03:31:02 UTC

Although pinging @here works pretty well too

2018-01-29 03:31:58 UTC

Ah okay. That's good to know @ThisIsChris

2018-01-29 03:35:40 UTC

If you're still here I need some clarification on a problem that I think I did correctly but it's not approving

2018-01-29 03:36:00 UTC

@Warren H sure!

2018-01-29 03:36:33 UTC

-2z - 4z = 19+ 4

2018-01-29 03:37:53 UTC

left side is -6z
right side is 23
so -6z = 23
divide both sides by -6
so z = 23/(-6) or equivalently z = -23/6

2018-01-29 03:38:28 UTC

Oh

2018-01-29 03:38:37 UTC

lol I didn't do the signs right. I got 23/6 that's why

2018-01-29 03:38:51 UTC

that'll do it

2018-01-29 03:39:16 UTC

ðŸ˜† it's really hard to pay attention to that sometimes. Especially on timed exams

2018-01-29 03:40:19 UTC

Yeah, best thing I could advise is that whenever you see a negative sign ANYWHERE, double check at the end that the signs look right

2018-01-29 03:41:32 UTC

if all the numbers are positive then you probably don't have to be too careful. It's just when a negative sign appears, keep going, but walk through it again at the end

2018-01-29 03:42:21 UTC

Yeah that's a good way to check. I try my best lol

2018-01-30 04:34:55 UTC

Anyone @here to help with another math question?

2018-01-30 04:36:05 UTC

I might could. I haven't done math in a bit, but I can do things like the last question posted.

2018-01-30 04:37:15 UTC

I know the answer to this question, I'm just not sure how to solve to get to it

2018-01-30 04:37:44 UTC

6/9 * 3/12 squared - 4/6

2018-01-30 04:38:24 UTC

Is there an equals sign?
