What's AE?

@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  

😆 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?

2018-01-30 04:39:01 UTC  

No. supposed to solve it

2018-01-30 04:39:13 UTC  

PEMDAS

2018-01-30 04:39:17 UTC  

I meant I knew the answer

2018-01-30 04:39:21 UTC  

Order of operations

2018-01-30 04:39:33 UTC  

Yep did that

2018-01-30 04:40:11 UTC  

Would a photo help for reference?

2018-01-30 04:40:15 UTC  

Yes

2018-01-30 04:40:17 UTC  

Yes.

2018-01-30 04:41:43 UTC  

How do I get 1/24?

2018-01-30 04:42:13 UTC  

When I multiply I get 54/1296 and i don't know how to reduce it because I'm bad at fractions

2018-01-30 04:44:07 UTC  

Simplify 6/9 * 9/144

2018-01-30 04:44:19 UTC  

The 9s cancel out

2018-01-30 04:44:33 UTC  

54/54 = 1 and 1296/54 = 24

2018-01-30 04:44:39 UTC  

And 6 goes into 144 24 times

2018-01-30 04:45:07 UTC  

So cancelled out the 9s and divide 6/144 ?

2018-01-30 04:45:12 UTC  

Is that mastering physics but for math

2018-01-30 04:45:16 UTC  

Yes

2018-01-30 04:45:36 UTC  

Or what @micbwilli said

2018-01-30 04:45:42 UTC  

Either works
