I don't get this math... I know most anyone would laugh and roll their eyes at me for being 22, and graduated highschool and not having the slightest idea how to solve any of these math problems. I am over here in tears cause I cant figure out fractions adn basic algebra. How the hell am I ever going to pass a test when I cant even begin to know this shit. It has been like 8 yrs since I have even seen this stuff and hell I barely passed it then... :tears
1 2/3 + 2 1/2- =

2 5/8 - 2 5/16=

12/5 divided by 7/12=

12z - 3 (z-6)

(x-2)(x-8) don' t the parenthesis mean you opposite it like remove them and turn the plus to a minus? that was my out on a limb trying to remember....

12a to the 3rd power - 6a divided by 3a


I mean I look at this stuff and it looks like something a 8th grader does but I don't get it! I don't know how to ask for help online here but no one in this house remembers or has seen it... hell my dad is 64 he doesn't know jack about this crap.... :banghead
Thanks for any help... it means so much :hugs

good luck. I think I got one of the problems but I wouldn't count on it. I suck at fractions and basic algebra

Ok for the first two cori, the first thing you want to do is make them into whole fractions, second you want to make those fractions have a common denominator.
Example: the first one

*to make 1 2/3 into a whole fraction, first multiply to whole number by the denominator, which makes 3, then add the numerator, that makes 5, so your whole fraction would be 5/3, now do the same to the second number.

*next you want to give them common denominators....

Ok I'll be back, watching LOST, waiting for a commercial :P

Thanks Renee... I will work on that one while you watching your show! :)

My math skills say the answer is 1/2 but we will see what Renee says since I suck at math :)

Ok so then the first one will be 5/3 and the second 5/2, so in order to give them a common denominator, the easiest way is to find the first number they both have in common, or that they are both divisible by. In this case, both 2 and 3 have the number 6 in common, 6 is divisible by both 2 and 3.

*for 5/3, in order to make the denominator a 6, you have to multiply the 3 by 2, however, whatever you do to the denominator you must do to the numerator. So you have to multiply both the 5 and the 3 by 2. This will give you a fraction of 10/6.

Now do the same to the next fraction.

*for 5/2, you have to multiply 2 by 3 in order to make it 6, so do the same to the 5. That makes it 15/6

So here is your final sentence:

10/6 + 15/6

OK BRB again, LOL

with the fractions you just find a common denominator - eg 2 5/8 - 2 5/16 can be written as 2 10/16 - 2 5/16. Then you just subtract as usual, so the answer would be 5/16

12z - 3(z-6)

12z - 3z - 18

9z - 18

(x-2)(x-8)

xsquared -8x -2x +16

xsquared -10x +16 (I think!)

Yea, I have all the answers just have NO idea how to get them :(
I don't understand this shit for anything.... What do I do with the negatives? Like the 1st question the last fraction is a negative... Oh my god this makes no sense... even reading it, it sounds like a foreign language... what is wrong with me :tears

I don't get how to make common denominators... I don't remember how... I look at my paper and all I draw is a blank. :tears

I'm sorry if none of this is making sense - I'm just working through them and putting down my workings. It's been years since I last did them and I really cant remember how to do the last one - sorry!

Ok now on the 10/6 + 15/6 that leaves you with a total of 25/6. You can also split the fraction by dividing 6 into 25, that leaves you with 4 1/6 as your final answer.

Does my explanation make sense? Sorry so long, but I don't like to just give answers, I want you to understand why you are doing what you are doing....LOL that's the teacher in me.

Oh no its not you guys... the algebra makes more sense than anything really....
I just am not grasping how to do it on my own... :(
I just dont comprehend math period... guess nursing probably wasnt the best goal lol but oh well....

ok, to get a common denominator you look at the bottom fractions and find something you can multiply with to make them the same - so with 1/3 and 1/6 you would multiply the top and bottom of 1/3 by 2 to make 2/6. If you had 1/2 - 1/4 you would multiply 1/2 by 2 to make 2/4. so 2/4 - 1/4 = 1/4

Does that make sense?

The first one is a negative? Usually the negative is in front of the number not behind it. if it really is a negative and I can explain to you how to solve for a negative. Read through my whole explanation first though, and let me know if it makes any sense, and what doesnt

Dont beat yourself up about not understanding it - my df is trying to explain a bunch of graphs to me at the moment but I dont get it at all, and I'm going to have to explain them to my boss on Monday - I feel like banging my head against a wall! We all have things we're good at and things that are difficult - it's what makes us different.

double post

OK Renee... after much trial and error I finally got "that" one! :)
Now on to the rest... yikes!!!!

OMG!! I went in there and tried the 2nd one using all that yall had told me and I GOT IT RIGHT FIRST TRY!!!!!!!!!! :d

Ok chica, regretfully I must get off here now, but if you still don't understand any of the rest tomorrow and still need some help, catch me on messenger ok, sdxicana, and I'll try to keep tryin to help ;), and don't worry, you don't have to be 'good' to understand the basic concepts. Once you get a few basic concepts, you'll be able to do many problems, you're not alone so don't feel bad, you CAN and WILL get it soon enough :)

PS: if you have ANY resources at all through the school you are going through to get any type of tutoring I highly suggest it chica, it can do wonders for you

yay! :cp

Ok... well I am not understanding the %s and integers and algebra equations sooo Im going to Luke's and he is going to re-teach this to me.... Thank God. :)

Hey- just wanted to chime in here... I absolutely LOVE doing algebra. In my high school class (that I took a year early) I got a 120% for the year... and I taught the class after the teacher was done with her lectures. College algebra I got a B and only went to maybe 1/3 of the classes! So any questions you have feel free to msg me and ask :)

Chrissy, wanna take Algebra for me? I'm math impaired lol....joking..kind of.
