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

Although pinging @here works pretty well too

Ah okay. That's good to know @ThisIsChris

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

@Warren H sure!

-2z - 4z = 19+ 4

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

Oh

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

that'll do it

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

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

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

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

Anyone @here to help with another math question?

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

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

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

No. supposed to solve it

PEMDAS

I meant I knew the answer

Order of operations

Yep did that

Would a photo help for reference?

Yes

Yes.

How do I get 1/24?

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

Simplify 6/9 * 9/144

The 9s cancel out

54/54 = 1 and 1296/54 = 24

And 6 goes into 144 24 times

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

Is that mastering physics but for math

Yes

Or what @micbwilli said

Either works
