Hi! Just pretend the letter stands for something. Like a+a=a2 Pretend
A stands for apples. theres 2 a's (2 apples) so 1 apple+1 apple=a2 (apples 2)

Hope this helps!

I understand the difficulty you are having, I am in year 7 too and I have had to help a lot of my friends with it because I am the only one in set 1.

Algebra is quite easy when you break it down.

You have terms, expressions and equations.

a term is a single letter used instead of a number. For example- a

an expression is terms and perhaps some numbers put toghether with a x / % / -/ +. It has NO EQUAL SIGN
example- a x b or a2 -b

an equation is an expresspresion with an equals sign.
for example- a x b=c or c could be replaced with a number.

a2 means a has been multiplied by a. This means it is a squared.

a +a= aa.

I hope this has helped you. If you need more help talk to your teacher.

basically, The Letters Are Like Extra Numbers You Have To Work Out Like

X(4+5) , Brackets Always Mean Times So You Have To Times Each Individual Number By XSo It Will Be 4X + 5X then you have to simplify it so it will be 4+5 = 9 so 9X

And When You Times X By X It Will Be XSquared And XxXxX Will Be XCubed

Any Other Questions Just Ask And Ill Help :D

hi iv got an exam 2morrow and i need help with mean and median!!!!
can anyone help!1 plezzzzzzzzzzzzzzz
Heyyaa!! im not sure of youve got a reply to this question already?? Anyway mean and median is reeeallllyy easy once you know how to do it properly....

MEAN....
say you have a set of numbers that you have to find the mean from like 2,3,4,5,6,7,8,9 for example all you you have to do is. Add all the numbers up (that makes 44) then divide them by however many numbers there are in the set (8) then youve got the mean (this one is 5.5)

MEDIAN....
This one is really simple!! If your set of numbers is 9,6,2,0,5,1,7 what you have to do is... Put them in order (easier to write them on the side of your work or on the table if nobodys watching...) which is 0,1,2,5,6,7,9 then put out two fingers (dont swear!!) andcount inwards eg. the 9 and the 0 then the 1 and the 7 and so on till you have no more pairs and a middle number (5 in this case BUUUT... if there isnt a middle number take the TWO middle numbers and and find the middle of them (if it was 6 and 8 left the mean would be 7) Hope this helps!!xx

WE DONT DO ALGEBRA TILL YR 8!

not true, depends what kinda school u go to. i go to a grammar school so we're a year ahead. also, in normal schools, they sometimes try to push u. may b different at ur school... i dno. but u can do algebra in year 7!!

algebra is simple. basically one number is hidden as a letter, any letter e.g o,p,q etc. In algebra they don't use a multiplication sign sooo 2y means 2 times y(this is when you are trying to find out what y or the hidden number is). when you add numbers in algebra its the same as when you add any numbers but the only difference is you cannot add a letter and a number together e.g 2y+2 stays the same
2y+2y is different however. Basically you can add the same letters together so when you add 2y with 2y you get 4y. 2y+y=3y because 2y means there are 2 y's so when you add another why in you increase the number of y's to make 3y

Hope this helped

hey x
I'm in year 7 too !
heres some tips for handling algebra:

Algebra is basically a way of shortening things, to make it easier. This is called simplifying equations.
For example: Seven oranges plus two oranges. That is quite long to write out, so I would simplify it to 7o+2o , then work out the answer, 9o.

In algebra, if you times something together, you do not put inthe times sign as this could be mistaken for a letter. For example, 7a X b. I would put: 7ab, missing out the times sign. When you write something to do with multiplying, always put the number before the letter. For example: WRONG; a7 , RIGHT; 7a

Why not try some activities on this, off of bitesize, [edited by moderator] or MyMaths!
Hope this helps!
From Olivia x

algebra has lots of stuff. I'm ok-ish at most of it, but I do have strong points which I'd be happy to explain.
take a question like 2 (3x - 4) + 4 (5x + 2) = 30
you have to do it in steps. now the 2 outside the brackets means you have to multiply what in the brackets. do the first set of brackets, and you get this:
(6x - 8) + 4 (5x + 2) = 30
next you do the second set of brackets
(6x - 6) + (20x + 4) = 30
next you have to collect like terms. like terms are basically stuff that is the same. e.g. put all Xs together and all numbers. then you get this:
26x - 2 = 30
then you have to get rid of the 2, so you add 2 to both sides of the equation.
26x = 32
then you divide both sides by 26. this will give you the value of x.
the answer is about 1.2, if you round it to one decimal place.
I hope I have helped!
oh, even though this question probably won't come up in an exam, a question like it will and so you will probably need to know the strategy.

Hi , again

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

Thx

Example 1:
(8+y)-2= say, 20
8+y= 20+2
8+y= 22
y= 22-8
y= 14
Example 2:
(8+2)-2=
(8+2-2)=
8
Do you get it now? Those were probably bad examples but I am a Year 7 girl too but my friends say that I am a maths whizz
I hope I helped.

when there are brackets you need to multiply
e.g (3x+2)
3*x=3x
3*2=6
3x+6=9x

there u go

Hiya!

I am also in year 7 and the top set of maths. My level is bad though: 4a - 5c... >.< I still find Algebra quite hard and all these posts have helped me too. I only registered a few minutes ago as I thought I could help you a little bit.

Okay, Algebra (like lots of you have already said) is mainly numbers represented by letters.

8c x c = 9c <--- The c is for Cows...yeah, weird. You start off with 8 cows and Freddie Farmer buys another Cow, resulting in Freddie Farmer having 9 cows. Baisically, 8 carrots or whatever, plus another. Fairly simple.

So, this next bit looks hard, but in fact, is easy! ^^

8n + 5n + 13 = 8n + 18 (I belive that you cannot add numbers to a Albebra sum can you? Like 2n x 13)

How to do it!
13 + 5 = 18 right?
18 + 8n = XXXXX You can't do it! Illegal!
So you keep it as 8n + 18. From my experience, you will get the mark. Affectivly, (spelt wrong) correct answer! But, if you are still confused, ask friends and teachers and your parents. Often, asking friends helps because they are near your age and most likely, your level in Maths too! I personally would ask friends first THEN go to my Maths teacher and my parents.
Hope this helps a bit with the basics!

Hi i hope this will help you with some types of algebra
e.g. 2a+11=21
to work this out you have to reverse what has been done to a like this:
(-11) 2a=10
(Divide by 2) a=5

Then it can get more complicated:
2a+14=9a+2
Then you think if you had two bags of sand and 9 bags of sand which would you move and you would move 2 because it is the lightest so
(-2a) 14=7a+2
and now it is like the easier ones:
(-2) 14=7a
(divide by 7) a=2

How this helped with solving equations

il answer this expanding brackets Q for you:

(8+y)-2
i'd rather write it like this : -2(8+y)

first you time -2 with 8 = -2x8=-16
then you times -2 with y = -2 x y = -2y
then you put it together ~ -16+-2y = -16-2y
since you cant simplify this any further you keep it like this.
hope this helped and if you still dont understand then just tell me

Algebra is just letters instead of numbers, so if you get an equation like

y= 7

Work out

3y+ 10

Just write it out as
3 x 7 + 10 =?

21 + 10=?

31

Hi , again

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

what you'll have to do is do the brackets first then which in this case is (8+y)-2
therefore the answer ends up as 8y-2 which comes to 6y in the end.
good luck :~)
