hi,i cant help you with negative numbers but brackets always mean do that first in maths

e.g (9+7)x2, i would do 9+7=16 then i would x 16 by 2 which is 32,is that ok?

remember BIDMAS
brackets,index,division,multiplacation,addition and subtraction. This is order of operation remember brackets always come first!!!!
Hope this has helped.

brakets are basically saying to do that first. negitive numbers are confusing, but you need to think simple here is a trick/ way of remembering
- - = +
+ - = -
- + = -
+ + = +

Remember BIDMAS - BRACKETS, INDECIES, DIVISION, MULTIPLICATION, ADDITION AND SUBTRACTION, IN A SUM THESE HELP YOU IN THE ORDER YOU NEED TO CALCULATE A SUM,
FOR EXAMPLE:
4+6x7-3
in this sum you would do the multiplication first:
6x7=42
then you would do the addition, since you have already worked a part of the sum out you would do:
4+42=44
you would then work out the subtraction by doing:
44-3=41

hope this helps! xxx

Hi I'm in year seven as well and with negative numbers it can be very easy if you remember these rules 1) subtracting a negative is like adding a positive 2) adding a negative is like subtracting a positive. Hope I helped

With negative numbers if you remember that two negatives or possitives added together will always equal a postative number and a negative add a posotive and vice versa will equal a negative number

Hope this helped

Hi,
Basically what ever equation it is, you always work out the sum in the brackets first. For example, if the sum was 4+(7x2) you would work out 7x2 first, which is 14, and then the equation would basically be in a simpler form "4+14". Then you can easily work it out from there. So the answer would be 18.

Hope this helps!

Posted by RoseGrinningLemur (U15558493) on Tuesday, 29th January 2013

whatever is in a bracket is separate from the rest of the sum. eg:

if you want to ask what 9 add 6 multiplied by 3 is, you might write it like this:

9+6x3

But the reader might add 9 to 6 multiplied by 3. To prevent this, write it using brackets like this:

(9+6)x3

You should always work out the value of a bracket first, so there won't be any confusion.

Hello, im in year 8, im cant explain negative numbers but with brackets you just need to times

E.G 9(8X+6)
You Do 9 times 8X and 9 times 6
72X+54=126X

I am in yr 7 as well, sorry I am totally lost with negative numbers too! But if it is any help to do brackets you would always use them to show which operation comes first eg.

(2+5)x3=21 you add the 2 and 5 which is 7 and then you times that by 3

its different to

2+5x3= 17 5 times 3 (15) then add 2

All you need to do for Negative numbers is remember:
Positive + Positive = Positive
5+5=10
Negative + Negative = Negative
-3+-3=-6
Ignore the plus so it becomes
-3-3=-6
Positive + Negative = Positive/Negative
5+-3=2
5+-10=-5

Brackets just mean do it first:
8
(5+3)-2=6
8
2x(5+3)=16
Hope this helps

Ok so I'm doing expanding brackets at the moment which is fairly complicated, or at least I think so. With brackets they basically mean do this first. So (5+5)/2=5 because the 5+5 are in brackets you have to do it first. Then 5+5=10 and divided by 5 is two because 2 5s are in ten. Negative numbers don't really exist but they are used to show how much money you may owe at the bank or what the temperature is. Hope this helps! :D

just use the bidmas rule 'b' for brackets which are always first and negative numbers are numbers which have a minus sign for example -1,-2,-3,-4 e.t.c.

Hi!!! Brackets and negative numbers are easy one you put your mind to it! BIDMAS helps with the brackets problemo as it shows you how to work out equations with brackets in! aso check out the order of operations in the ks3 section!
Negative numbers-easy! Just work on a number line!!! When you add posotive numbers (0 and above) you move right on the number line! Adding negative numbers, you move left! Look on the Negative Numbers section in the ks3 place!

If you are stuck with multiplying or dividing negative numbers, hopefully this helps!

Positive X Positive = Positive

Negative X Negative = Positive

Positive X Negavtive = Negative

Negative X Positive = Negative

And divide....

Positive / Positive = Positive

Negative / Negative = Positive

Positive / Negavtive = Negative

Negative / Positive = Negative

Hi AmberBubblyMango!
I'm in year 9 at the moment, and I understand your concern with negative numbers.
If you are adding two negative numbers together, then the answer is negative. e.g
-3 + -2 = -5
-56 + -1 = -57
You need to pretend that they are positive numbers, and then add the - sign.

If you are subtracting negative numbers, for example -2 - -4, then you add them together - minus a minus equals a plus. SO this would be -2 + 4 which equals 2.
If it helps, use a number line, and find where the first number is, and add on or subtract from there.

Brackets are simple - BODMAS/BIDMAS - you work out the brackets first. Multiplying brackets is more complicated. If you still need help, post something else...
Hope this helps!

IN a nutshell:
Negative x negative = positive
Negative x positive = negative
positive x positive = positive

negative/negative = positive
negative/positive = negative
positive/positive = positive

negative - negative = negative + positive (e.g -3 - -4 = -3 +4 = 1)

don't worry-
2. when doing algebra try to make it clear so you can see your mistakes
3. for example 6y+7+2y+45+12
I would try to ring around the numbers
-- (6y)(+7)(+2y)(+45)(+12)
you can then move these around--
6y+2y=8y
(+) 7+45+12=64

negative numbers is a lot easier than you think. the only riles you have to remember are:
1) positive number x negative number = a negative number
2) negative x negative = positive
3)adding a negative means subtract ( go down the line )
4) subtracting a negative means add ( go up the line)

hope this helps, if you need any help let me know

When adding or taking away with negative numbers think of a number line or thermometer. Remember that its the opposite with multiplying and dividing.
For the brackets just remember the order of operations. BODMAS. That's Bracets, Power Of, Division, Multiplication, Addition and Subtraction.
If you still don't get it your school will probably have a Manga High account. Ask your teacher about it. Just search the school index on the site. :P

Hi i used to struggle with this too but luckily with a bit of help from my maths i am now an expert! I find the easiest way to remember negative numbers is to draw out this table: X+-
++-
- -+
It helps me a lot in maths and to remember how to do brackets i use BODMAS
this tells you what order to do things in e.g.: brackets open, division, multiplication,addition then subtraction.
If my helpful maths skills still don't get your brain around these topics then either visit your teacher to get a mymaths password or go online to get one yourself(unfortunitally there is a small charge if you get a password online) but my maths is worth it as it helped me with many problems. I hope i was a help Megan x
