Beginners $A$ lgebra Series

i am making a algebra problem series covering the basics of algebra also please use this note to report any problems (Note this is based on Algebra taught in Sydney NSW Australia may differ in other States/Countries do not take this as a study guide this is just tips further studying is recommended)

Basic Fundamentals of Algebra to always follow by Coming soon!

Problem 1

Problem 2

Problem 3

Problem 4 This is a draft saved as a discussion and will be posted as a question in 5 days when it is completed you can read it for now in the meantime : )

Homework Questions Series (Once i have released all example questions i will start releasing questions based on what i have discussed in the questions for you to practice):

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

@Percy jackson would you like to solve my latest addition?

NSCS 747 - 7 months, 2 weeks ago

what about you @Frisk Dreemurr what about you?

NSCS 747 - 7 months, 2 weeks ago

@Frisk Dreemurr ?

NSCS 747 - 7 months, 2 weeks ago

Solved all three, but they're too easy for me, like they're 7th grade level bro

A Former Brilliant Member - 7 months, 2 weeks ago

ik that what year they r based fpr

NSCS 747 - 7 months, 2 weeks ago

@Nscs 747 – Hi (some text)

Half pass3 - 7 months, 2 weeks ago

@Half Pass3 – hello

NSCS 747 - 7 months, 2 weeks ago

@Nscs 747 – all solved, easy👍🏻

Half pass3 - 7 months, 2 weeks ago

@Half Pass3 – : )

@Brilliant Mathematics do you like my algebra notes?

NSCS 747 - 5 months, 3 weeks ago

These are good. The next step is to apply real life examples to demonstrate the importance of algebra.

Brilliant Mathematics Staff - 5 months, 2 weeks ago

Wow, you actually replied. You know I thought you were busy taking down jokes and having a bad sense of humor 😑

A Former Brilliant Member - 5 months, 2 weeks ago

@A Former Brilliant Member – I know.

Brilliant Mathematics Staff - 5 months, 2 weeks ago

@Brilliant Mathematics – Alright, I agree you won't be taken very seriously if you joke all the time...🤣

A Former Brilliant Member - 5 months, 2 weeks ago

will do

NSCS 747 - 5 months, 2 weeks ago

wait wdym by real life example u mean like jack had ab and gave lisa a those type of questions? or like scenarios in when to use this skill

NSCS 747 - 5 months, 1 week ago

@Nscs 747 – Yes. $\quad$

Brilliant Mathematics Staff - 5 months, 1 week ago

@Brilliant Mathematics – Whic one the first one the second one or both

NSCS 747 - 5 months, 1 week ago

i propose to add brackets in your problem 2. like Lâm Lê said: --7 or even +-3 is very uncommon. maybe it is a very new thing, but i've never seen it.
annotation: the commutative law ab=ba is valid in your problem because its about real numbers. if it were about matrices then this is not always true.

num IC - 5 months, 1 week ago

I don’t know what matrices are I’m just basing it on year 7 maths I have learnt at my school

NSCS 747 - 5 months, 1 week ago

yeah i know, i just wanted to inform you that there are things in maths where the commutative law cannot always be used.
so i value that you mentioned a* b=b* a in your introduction.

regarding the other remark:
does your teacher use --7 ? or does he/she use -(-7) ?

num IC - 5 months, 1 week ago

@Num Ic – we use either but in basic introductions of algebra you learn that the operation always belongs to the term that comes after it i will edit it today since i am on computer

NSCS 747 - 5 months, 1 week ago

@Nscs 747 – yeah no problem. i was just curious. (i'm sorry if it sounded like a claim)
i have never seen --7, so was eager to know if there was a new notation introduced.

num IC - 5 months, 1 week ago

@Num Ic – - - 7 the - on the right belongs to the term on the right of it which in this case is 7 since there is another - in front you can easily in your mind change it to a + because of the double negative

NSCS 747 - 5 months, 1 week ago

i just recognized that there is a small 'L' missing in your title

num IC - 5 months, 1 week ago

@Num Ic – oh bruh how have i not noticed that for 2 months

NSCS 747 - 5 months, 1 week ago

@Nscs 747 – so it is intentional? bcs problem 2, 3 and 4 still missing an 'l'

num IC - 5 months, 1 week ago

@Num Ic – No it’s that u know how it saves the names I use for the problems I just did that instead of typing them seperately

NSCS 747 - 5 months, 1 week ago

@Nscs 747 – ok. i just was not sure if you wanted to leave it like that bcs it's funny or if you have overlooked it.

num IC - 5 months, 1 week ago

@Num Ic – I just overlooked it

NSCS 747 - 5 months, 1 week ago

@Num Ic – I will fix it in 3 days when I am on a. Computer

NSCS 747 - 5 months, 1 week ago

good idea to use another font for the 'A'. that creates a special look.

num IC - 5 months, 1 week ago

@Num Ic – ye i use it to represent like how in textbooks the algebra lettera are in a different font

NSCS 747 - 5 months ago

@NSCS 747 $--x$ is a little unclear. Plz do $-(-x)$ .

Lâm Lê - 7 months, 2 weeks ago

I don’t really put it because in algebra they teach you that the symbol always belongs to the value on the left as a basic rule but if you want I can do that
