It’s okay. It’s just one picture.

#22

for the four 4s are exponents allowed? does it have to be fourth power

#23

Yes, like 4^4 (which is a big number)

However, you may do: 4^(4 - 4/4)

Aw snap, I forgot one rule.

You are allowed to do .4 (4/10) and .4 repeating (4/9)

#24

oh ok cool

#25

I’m gonna start working on this again

If you do have an idea to add, tell me, because I might also be editing the Global posts. Thanks

#26

What is coan doing? I need to confront that sneaky duuuude

#27

Aw man, why did I run out of edits

I didn’t know that was el poseeble

I want to edit my topic
I’m gonna do it on a PM because it doesn’t count there, and then wait 18 hours to add a bunch o stuff

What would a 4D dude look like in a 3D world? Normal? Or weird?

#29

What would a 3D person look like in a 2D world?
Idk probably considers abnormally screwed

Lol

#31

I don’t know, go live inside a Game & Watch to find out!

Hi @JonnyGamer, right now I am a 7th header in pre-algebra and I kinda want to start some Algebra 1 stuff. Is there any significant gaps between the two? Thanks.

#34

Algebra 1 is harder sometimes.

#35

Yeah but right now pre-algebra is really easy for me, and it’s time I make the jump.

#36

Algebra is just some advanced pre algebra, it’s all the same though

Do you know how to solve formulas like:

x/4 = 17
or
(5x)/3 = 72

#37

Well the first one is just multiplying 17 by 4. While the second is what I don’t actually get.

#38

Okeedokers no problemo
The second is written as:

5x

— = 72

3

this should help some

#39

No. I’m like halfway through algebra 1 and its basically the same. Without the !omg division

#40

Second is (73·3)·5=x
