Need help on math hw Should be easy
So before I start, I'm in 10th grade, and I literally forgot all of this. And on the other hand, we took NO notes in class, my teacher just gave it to us. (Sorry if it's a lot!) i'm really confuzzled . Thanks to all who can help! I mean I remember all of these, just forgot how to do it.. I think we use PEMDAS but idk
Instead of typing it out, I'll post a picture so you can get a visual look at it .
P.S if my answers are incorrect, correct them :o? thanks ;D

Lol yeah I forgot, but now I understand it now thanks to helpers ^.^. <3
You seriously forgot how to do this? Shame, shame. You can just use your graphing calculator...
oh my god this thread.
@sellinscrolls I'm in adv geo.
This is just preview works on what I should already know I just forgot haha
what exactly do all of you guys gain from insulting OP's intelligence?
This is basic math dude. No offense though.
But, shouldn't you be in Geometry by now?
</3 o.o
17 is -44
You're in 10th grade and you're taking algebra?
[quote=Coordination]@icemage11 i been having -82 xD.
@naturaltears i got the same answers for like 14-16, but ice said i was wrong? and number 17, recheck the problem there int (10-1(1)) or whatever[/quote]
you have a negative on those numbers (:
and i'll get to you back! i'm kinda busy
@icemage11 i been having -82 xD.
@naturaltears i got the same answers for like 14-16, but ice said i was wrong? and number 17, recheck the problem there int (10-1(1)) or whatever
@Coordination: It's fine - you'll get the hang of it! Practice makes perfect! If you need any help feel free to PM me!
10: (-7)-((-5)-10)x(-5) = (-7)-(-15)x(-5) = (-7)-75 = -82
@icemage11 DUH -7! xD What about the others? im serious i get the same answers
and @naturaltears it honestly means A LOT you're helping me! almost the whole class is failing and its the 2nd week of school. we're not dumb, but its the teacher
@Coordination:
Go to page 4, I've done the solutions for some of the questions you're stuck with.
I'm still doing them!
It's not 7.
2-5-(-6)-10 = -3+6-10=3-10= -7.
@metaghost4 shhh
@icemage11 i need help! My answers arent changing! the only one that changed was number 5. my answer is 7
@trumanb my school is dumb
I wish my grade 10 math was this D:. When I went into grade 10 from 9... major math lvl change D:. < So I ended up with a really low mark QQ- plus most highschool teachers sck. -.-. Well I'm going into grade 12 now.. I did ok in 11 once I got used to it .
Edit: I also noticed a few common mistakes you made. if you see -(-5) < just change that to +5
@icemage11 ughh ill keep trying !
@naturaltears me too, its so easy, but now i forgot
SIGH.........i miss these kinds of math.........
5.
2 - 5 - (-6) -10
= -3 + 6 - 10
= 3 - 10
= -7
7.
(-4) x (-2) + (-8) - (-6)
= 8 + (-8 + 6)
= 8 + (-2)
= 8 - 2
= 6
9.
(-6) - ((-5) + 7) - 2
-6 - (2) - 2
= -8 - 2
= -10
12.
1 - -16/(5-9) <- first you want to make the 1 have the same denominator as the -16/(5-9) so times (5-9)
= (5-9)/(5-9) + 16/(5-9)
= 4/4 + 16/4
= 20/4
= 5
14.
You're almost right, but you need to make sure you subtract/add properly.
= -2 - (-10)
= -2 + 10
= 8
15.
2 - (7 + 5 - (-4))
= 2 - (12 + 4)
= 2 - (16)
= - 14
16.
((-5) - (9 - 3)) x (-5)) <- because of BODMAS (or whatever), you'll need to solve the first part since it's in brackets
= ((-5) - (6)) x (-5))
= (-11) x (-5)
= 55
17.
(10 - 1(-1)) ((-7) + 3) <- do brackets first then MULTIPLY.
= (10 + 1) (-4)
= (11) (-4)
= -44
5, 10, 14, 15, 16, 17 is still wrong. At least you're improving
@djhfreak yeah i knew that already, but i just didnt know when to do it, but now i do . <3
@Coordination
Whenever you see two negative (-) signs, it basically means that you're adding. So for example, 5 - (-4) = 9, because 5 + 4 = 9. It's the same vice versa, (-5) - (-8) = 3, because (-5) + 8 = 3.
@icemage11 Idk how to do 12, it has 2 " - " signs .-. ill post up a comment of my new answers ( i got them now)
@djhfreak i know its just review and i snoozed lol and thanks
Edit: @icemage11 these are my new answers
1) -2
5) -1
7) 6
9) -10
10) -2
11) -7
12) idk how to do
13) -24
14) -8
15) i still got -32
16) -55
17) -40
Just letting you know, this looks like math for Grade 6 and 7.
Number 15 is (-14).
@icemage11 what the fudgeee <l3 number one is -2 right
@ecliptic no i actually know it but for some reason im tweaking right now o.o
[quote=Coordination]@ecliptic i know ! I just simply forgot[/quote]
You forgot basic math?
1, 5, 7, 9, 10, 13, 14, 15, 16, 17 are all wrong.
Where's 12?
@ineqt, thanks i know that already though but it kinda helped me with the -8-(-10) one ^.^
Remember that negatives negate each other. So -8-(-10) is 2 since it's -8 + 10. Also you probably know this but follow PEMDAS. Although M and D/A and S are interchangeable depending on which comes first. So sometimes you do division before multiplication or Subtraction instead of addition first.
I would check them for you but I don't wanna strain my neck or turn my laptop to write them down. Good luck though Glad to see at least someone is getting their homework done
@ecliptic i know ! I just simply forgot
Dude, how can you not do this....
YOU ARE IN GRADE 10, this is like grade 5 stuff, not even
@fun2killu sowwy
EDIT: added one with answers! check?
@Coordination: no need to be rude sir!
@fun2killu shut up
@metaghost4 omg i hope u remember me xD i think we're added here and i've been doing nothing, teacher is making us learn something different i just snoozed
anyways, whats up with number 12? havent seen one that has 2 "-" in a row
@exusia nope in adv. geo. just right now its beg. of school so we just learning what we already know
@Coordination: excuses, excuses
@noobsnipe haha thanks! and im good at math, just this time i snoozed x.x.
@lowwillpower thanks man
ill post up another ss of my answers soon
[quote=Coordination]@cindertea thanks ^.^
@fun2killu i did, but it comes up with the basics, which i know already. i just need help with ones that have 2 parenthesis and brackets and parenthesis.[/quote]
Even double brackets still falls within simple order of operations. Do things within brackets before using the bracket context as part of another operation (e.g. 4(3+(7x(5+8))), start with 5+ 8 = 13, then do 7x13 = 91, then 3+ 91 = 94 and then 4x94 = 376).
thanks to all u guys above ^, starting to know it more!
@fun2killu my internet is slow a'f .-. <l3
@Coordination: you can find rules on how to do them, just sayin'
@cindertea thanks ^.^
@fun2killu i did, but it comes up with the basics, which i know already. i just need help with ones that have 2 parenthesis and brackets and parenthesis.
Yeah it's all bedmas/pedmas and rules of operations.
you really could have just googled order of operations... just sayin'
@icemage11 and @onelife thanks! I'm so stupid, i should know these and i do.-. I hope theres a way I can PM you guys, haven't used basil in a while. and
@ineedhelpplz lol i wish, but this teacher freaky
@foxes what about like number 13 xD
@Coordination: its 13
#8 is not 21.
3 + 6 - (-8) - 4 = 3+6+8-4 = 13.
@onelife i dont even know
i think 8 is 21 unless im doing it wrong
@icemage11 it is, i mean I remember all of these, they're easy, but i havent touched them in so long and thanks ;D
edit: got number 1 now
This looks like grade 6 to me o.o
Anyway, 1 and 7 are wrong.
