algebra is just numbers but its diguised as codes like y times y is y2!

BTW i'm also in yr 7 so i'm not that good! =P

Algebra is dead easy once you get used to it. Have you tried this website or have you asked your teacher if you don't understand? Maybe you should ask your parents. If you are still having trouble just ask me, I can easily help you with Algebra.

Good Luck!

You could say algebra is solving equations, rules, etc.

ok algerba is missing numbers thats it. and equations that simplify what you want to do with then.

ok first multiplying.
example: x times 3.
ok so first what is multiplication. it is basically 3 lots of a number example 3times 3 is the same as 3+3+3 so its the same with x. so x times 3 = x+x+x or simplified to 3lots of x or 3x

next sums:
ok first example:
x+3-5=20.
ok so you swap the signs around (ex.+becomes-, -becomes +.)and then the sum example
20-5+3=x next swap symbols 20+5-3=x so STEP1:20+5=25,STEP2:25-3=22 so x=22 lets try the sum now x(22)+3-5=20 , step1:22+3=25, step2:25-5=20.

next whole sums:
3x+6/2-4=11
ok first simplify (only do this if you have to or it helps)so 3x=x+x+x then useing bidmas (below.) 6/2 which is 3 so the sum is 3x+3-4=11 then swap it so 11+3-4=3x then the symbolsdont swap the 3x though so 11-3+4=3x, step1:11-3=8 , step2:8+4=12 then divide that by how many xs you got so thats 3 so , step3:12/3=4.
3x(4)+6/2-4=11 step1: 3 x 4=12, step2: 6/2=3 step3:12+3 =15 step 4:15-4=11. done.

hope it helps.

Hi , again

You see I don't get things like (8+y)-2 and all that stuff. My teacher says its expanding brackets.

Thx

Here's a cool little trick I like to call the balance method. Say, if you have a question like: 2y+2=1y x 3 work out the value of y ( very simple question).

2y + 2 = 1y x 3
---------------------

Here's your balance line. The balance point of the equation is at the equals sign. All you have to do is find the lowest value of y which is 1y on the right. Subtract the whole value -1y- from itself and the 2y on the left. Now you have:

1y + 2 = x 3
-------------------

Now just get rid of the multiplication sign...

1y + 2 = 3
------------------

Subtract the 2 on the left from the 3...

And you have the value of y. If you had more than 1y......

6y + 2 = 3
-----------------

You'd take the two from the three and divide it by 6......

(3 - 2) / 6 = - 2

Hope u get it!!!!!

Algebra is really easy, if you fully understand it! I'm in Y7 myself as well, and we are currently learning Expressions with equations. My teacher's method of doing this is quite easy actually.

But first, lemme explain expressions:

7a+8b+9y = In this expression, there are no LIKETERMS, so therefore you cannot SIMPLIFY them. (These two words are important in algebraic expressions). LIKETERMS is when you find, the two that have the same unknown number. Is the value of 'a', the same with the value of 'b' and 'c'? Noooo…. )

7a+5a+7b = In this expression there are LIKETERMS and you can finally simplify this expression. So just group the expressions together, 7a+5a = 12a. (Don't forget when you are grouping LIKETERMS, you have to join them with the operation - so if we were to change 7a+5a to 7a-5a, you would obviously have to take away 5a! But if the LIKETERMS are mixed up like this; 7a+7b-6a, the 6a would go with the subtraction sign.)

SRY IF THIS IS CONFUSING!! So hard to put in words lool.

An expression is like a formula it doesn't have an equals sign.
e.g:
4x+2
An equation has an equals sign :
4x+2=16
Algrebra is easy once you get used to it , I found it hard first too. But you just need to practice lots ! =) Try buying revision books/cds from school or stay for revision classes after school

don't get stressed over algerbra believe me i did and it didn't get me anywhere it will come eventually .i was rubbish a maths but then i got help from my teachers and this website, i had a maths test once on algebra and i was terrified because i thought i would get a really bad score but when i got help i didn't do to bad.so if you just believe you can do it then you will.
algerba is just letters disguising numbers, here's an example

5y+3y=8y

i hope this helps a lot!

and good luck with your algerbra!

Right, algebra is basically swapping a letter into where a number would be. You can't explain in writing so you need to visit some websites such as BBC Bitesize, Sam Learning or MyMaths. Although these sights are not the funnest place to be on the internet, they help you learn lots. If you are still having trouble, privately ask a maths teacher at your school for some extra help at break or lunch or after school

(8+y)-2 was you're question right? Well, everything you have inside a bracket has to be multiplied by whatever is outside the bracket in this case... (8X-2)+(yX-2)

its basically replacing numbers with letters so you just have to figure out what the missing number is for example its similar to 4 + _ = 8 you know the answers 4 it could also be written like algebra would 4 + y = 8 what is y ?

Hi! I'm not sure if your still confused but I'd gladly help!

I'm in year 9 and I seriously suck at maths, though I seem to do well in algebra and I got a fairly good mark on my last test! (Plus I'm used to helping as my friend is continuously bugging me to help her!!!)

Ok, so algebra, as many people in this post have said, is basically substituting numbers for letters! Say you had a question:

5d+3t+d+8t=?

Ok this is an easier one but some questions like this look so hard you panic (I always panic in tests!) but you just have to keep your cool and concentrate on what the question is asking. Look at the d's first, it's basically 5+1 right? So that would make 6d. Then the t's, it's essentially 3+8! So that's 11t!

Then all you need to do is put both your answers, 6d and 11t, and put a plus symbol in the middle! So the answer is 6d+11t!

This used to confuse me a bit, if you have a question like this:

7e-2h-4e+h+6e=?

What I used to think was, "WHY ARE THERE MINUS SIGNS AND PLUS SIGNS?!?!?! IT'S SO LONG I CAN'T COPE ARRRRRGHHHH!!" But that's changed! Just concentrate on the e's first (step by step is the way!). All it's saying is: 7e-4e+6e. Just look before each e to determine the way you firgure it out! Now 7-4 is 3 and 3+6 is 9. So that's 9e!! Just remember to look carefully as I have lost precious marks in the past by adding when I should of taken away!! And then for h it's simple, 2+1 which is 3! All in all, thats 9e+3h (looking before the next e before I determinded whether the final equation was a plus or minus!)

I'll also mention expanding brackets! It's confusing at first but once you get the hang of it you should be fine! Say you had:

4(y+8)=?

First, we simply times the 4 and the y (if there is a number infrount of the y then you would times that too. e.g 4(3y+8) would be 4 times 3y) So 4 times y is 4y! Then we do 4 times 8, which is 32! So the answer is 4y+32! (Remember BIDMAS or BODMAS for harder questions!)

If you're still stuck, I'm sure your classmates, teachers, family and people on bbc bitesize will help out! bbc bitesize is really good, but another good site to use (if your teacher hasen't told you about it already) is [Unsuitable/Broken URL removed by Moderator]. I hate having to do revision but these sites are useful!

Hope this helps! And good luck with the rest of secondary school!! :D

Algebra is really easier but people always ask me for help because they are struggling and i never understand how, even my 6 year old brother (in year 2) knows it because you just use things like apples
a+a+a=3a i.e 1 apple + 1 apple + 1 apple = 3 apples
2a x 3a=6a because 2 x 3 = 6 you just add a
7y+3a+1y=8y+3a because you add the same letters together, get it?
Hope this helps and good luck xxx

hi,
Im in year 7 aswell. we have bottom set, middle set and top set. Im in top set. If i was you i would be confirdent with your answers and trust your self. If you are really stuck ask your teacher what you could do to help. What helped me was to revise in a collins math book, it really helped. Or you could ask for a bit more home work on algabra. Your probably thinking " na, i dont want to do extire work". Trust me and try to do my advice.

Thanks, and i hope you are the best in your class.

Dont worry, algebra i very easy once you get the hang of it, i found i difficult at first but not any more. Hope this helps...
You will find algebra in many different forms and sums so its important to know/understand at least one type because then you will find it so much more easier to recognise the other types.
By using algebra it represents a number in the sum, eg-

n x 2= 4
n= 2

However you can also find algebra in not only a simple sum like the one above but with using shapes, eg-
If you have a square (all the sides are the same) and 3 sides equal 4 and one equals "n" then its like common sense all you do is figure out what the next possible number can be.
