New on Brilliant: Brilliant Squared

Hey everyone – we want Brilliant to be around for a long time, and to continue building a great product for you. Part of how we plan to do that is by offering a subscription version of Brilliant – called Brilliant Squared – with some special features to make it more awesome for members who subscribe.

Our vision for Brilliant Squared is to offer a structured path to improvement in particular topic areas, and a more powerful interface for saving and measuring progress. Our first two Brilliant Squared features that we are releasing today are more Practice maps, and a built-in scratchpad and calculator on every problem. We are continuing to work on more maps and features for Brilliant Squared members, and expect it to evolve a lot over the next weeks and months.

Brilliant Squared is still in its early stages, so we are offering introductory pricing for members who join Brilliant Squared before June 2014. We hope you enjoy it, and tell us your feedback.

We want most of Brilliant to remain free. As a free user, you’ll still have access to the community's awesome problems and notes, just like you always have.

Thanks to everyone for helping us build a company that we hope will grow and last to serve this generation, and many future generations.

This \(\text{Brilliant}^2\) is a great idea folks! We all know the hard-work the staff does. Subscribing to \(\text{Brilliant}^2\) is the least thing we can do to thank them. Of course, Brilliant has to find a way to earn.

\(\text{Brilliant}^2\) is the best way. I would have been disappointed if any other way would have been there.

How about, exchanging some points for free subscription (e.g. 10000 points for a month)? :P

Log in to reply

Hi Shabarish – not at the moment, but we will consider adding something like that in the future. In the meanwhile, you can see more details on how the scratchpad works here. The maps in other topics work just like the Algebra map.

May I know if the algebra map is what the practice algebra thing is?

Krishna Ar - 3 years, 7 months ago

@Krishna Ar Hi Krishna, yes it is. Free members get access to the algebra map in Practice. Brilliant Squared subscribers get access to additional maps in Practice.

Suyeon Khim Staff - 3 years, 7 months ago

@Suyeon Khim Thank you. :) But my question is - " does this have theory also"? This is because, Practice Algebra has only problems

Neil Ryan Manolong - 2 years, 5 months ago

Can we get a look at the maps themselves, without getting to solve the questions in them. That would let me (and others decide) whether to buy or not.

For example, what are the specific topics and sub-topics covered in Advanced Algebra? Conics, Vectors, Series, Mathematical Induction, Binomial Theorem are some that come to mind. But knowing the specific topics would really help.

Star Light - 3 years, 7 months ago

Log in to reply

Hi Star,

Advanced Algebra sections are: Complex Numbers, Complex Conjugates, Completing the Square, Partial Fractions, Polar Coordinates, Algebraic Identities, Parametric Equations, Algebraic Manipulation, De Moivre's Theorem, Arithmetic and Geometric Progressions, and Vieta's Formula.

In some cases, these sections cover more advanced versions of the material than are covered in the Algebra map. We are also working on the following sections for Advanced Algebra: Factorization, Algebraic Manipulation, Systems of Equations, Olympiad Polynomials, Olympiad Exponentials and Logarithms, Olympiad Absolute Value, Olympiad Functions, Olympiad Complex Numbers, Olympiad System of Equations, Olympiad Inequalities, Olympiad Polynomials, Diophantine Equations, Mathematical Induction.

Calculus sections are: Functions, Function Operations, Sequences and Series, Limits of Sequences, Limits of Functions, Algebraic Differentiation, Transcendental Differentiation, Differentiation Rules, Higher Derivatives, and Extrema.

We are also working on adding the rest of a typical Calculus curriculum, which has too many sections to list here.

Combinatorics sections are: Rule of Sum, Set Notation, Rule of Product, Systems of Equations, Venn Diagrams, Permutation Without Repetition, Principle of Inclusion and Exclusion, Combinations Without Repetition, Recurrence Relations, Probability, Set Notation, Counting by Complement, Venn Diagrams, Binomial Coefficients.

We are also working on the following sections to add: Bijection / Injection / Surjection, Counting Without Restriction, and more advanced versions of many of the sections already mentioned.

Suyeon Khim Staff - 3 years, 7 months ago

Log in to reply

Some sections in Pre-Calculus Maths seem missing (neither in available nor under development):

Conics: Circle, Ellipse, Parabola, Hyperbola Trigonometry: The Works: Basic Definitions, Basic and Advanced Identities, Solution of Triangles, Graphs, Angular Movement Functions: Transformations, Scaling, Inverses, Horizontal Line Test, Vertical Line Test Pre-Calculus Linear Algebra: Vectors and applications to geometry, matrices, determinants, area of triangle via determinant Geometry: The works Binomial Theorem Series and Progressions: Arithco-geometric series, harmonic series, exponential series, logarthmic series Complex Numbers: Argand Diagrams

I am aware that there are thousands of more topics in maths - just trying to reconcile your maps to a comprehensive maths syllabus pre-calculus.

Star Light - 3 years, 7 months ago

Log in to reply

Mathematical Induction and Diophantine Equations seem lost at the end.

Should't they be available before the Olympiad series starts - considering that that particular series would be quite tough if you do justice to it. You can always add an Olmypiad version of it for more difficult problems

Star Light - 3 years, 7 months ago

Log in to reply

@Star Light Agreed. These are not necessarily listed in the final order that they will appear, they are just the sections that are under development.

Suyeon Khim Staff - 3 years, 7 months ago

Log in to reply

Thanks. Seems quite detailed. Adding more sections will certainly make it more attractive.

One more question: The next logical step in calculus will be to add Integration. Are you also planning to add Multi-Variable Calculus / Differential Equations thereafter?

Star Light - 3 years, 7 months ago

Log in to reply

@Star Light We may add sections on Multi-Variable Calculus and Differential Equations, but Integration will definitely happen first. After that, it depends somewhat on what topics are in the highest demand.

Suyeon Khim Staff - 3 years, 7 months ago

I love this idea! The costs are reasonable for me :D

If you are thinking of starting a Practice Maps on Chemistry, it would be my honour if you include my problems on basic physical chemistry here.

Good Luck and All the best for this site that helps many of us and the next generations!

Christopher Boo - 3 years, 7 months ago

I know you guys do need the money to keep the site operational but I feel that either each practice map should cost $3.14 individually as a one time payment or that it should cost $3.14 a month without being forced to pay for 12 months. Anyone who buys that package will get through the practice maps probably in the first month so it makes sense to just make it a one time payment for each individual package. It doesn't seem like a product that needs to be renewed over and over. Realistically I think you guys will make more profit by having a lot of people buying a practice map package at $3.14/month one-time than you would from having very few people buy all 3 packages for 12 months for $37.68.

Cole Coupland - 3 years, 7 months ago

I think the pricing is quite reasonable - at least compared to competitor sites for children (www.ixl.com comes to mind) that charge $100 a year.

Also note that pricing is different for different countries - a really nice touch since the dollar pricing is for countries that earn in dollars.

Star Light - 3 years, 7 months ago

Log in to reply

I do think its reasonable I just don't find the commitment of 12 months appealing. Its quite a long time and I really can't predict how active I will be on the website so all I think should be done is to change it from a yearly to monthly commitment. I think I'll also wait for multivariable calculus and differential equations to come out. I really like that they decided to include the subscription feature because before this they were building the website with not much profit. I really don't know if it would be effective financially but I really think the number of consumers will increase greatly if it is changed from yearly to monthly commitments.

Cole Coupland - 3 years, 7 months ago

Log in to reply

I would like to retract my previous comment. Before I thought it cost $3.14 for 12 months for the practice sets and $6.28 for one month for the scratch pad. I didn't realize that they both came in either package you chose. I think I thought this because of how the prices were aligned on the page before. It definitely is more than reasonable.

Silas Hundt Staff - 3 years, 7 months ago

@Silas Hundt One thing I noticed is that it said you lose all your progress if you don't resubscribe to B^2. I do agree that you should no longer have access to the practice maps but I think wiping all your progress is quite harsh and even if you aren't a member for one day you are back to square one. Maybe I misinterpreted the statement but could you please clarify it?

Cole Coupland - 3 years, 7 months ago

@Cole Coupland Hi Cole, we do store the data for 30 more days after you're not a Brilliant^2 member, in case the subscription has lapsed accidentally.

Silas Hundt Staff - 3 years, 7 months ago

Log in to reply

Yes I saw it. It looks interesting but I don't really have a need for it, I use scrap paper for all of my questions. I am sure lots of other members on the website will want to use it though. I know there are quite a few members who work only on their computer and mobile devices so it should make it easier for them to work electronically. It should be appealing as well since it is only a monthly commitment.

Cole Coupland - 3 years, 7 months ago

I think it would be nice if it was possible to pay with PayPal. Also, since 3.14 $ is about 2.28 €, I don't think it's fair that european users have to pay 3.14 €.

I like the fact that the pricing is customised as per country.

Lots of sites price their services in dollars (at a price point suitable for US customers) and it becomes too expensive for everybody else.

Star Light - 3 years, 7 months ago

Log in to reply

I have some feedback on the way in which the practice maps are structured. I find that there is a mishmash of topics - although the topics themselves seem to be relevant.

For example: Calculus: The map starts with a skill on "identity functions". This, along with other basic skills should be taught in Algebra / Advanced Algebra.

The Combinatorics map has a large number of skills on equations and sets. While these skills may perhaps be as foundational skills, they do not belong in that map. They belong in a map on Algebra (or perhaps Miscellaneous).

Some re-organisation of skills would be highly appreciated.

Minimario Minimario - 3 years, 7 months ago

Log in to reply

Algebra was the first map we ever built, and it applies to a large number of people, since most students start learning Algebra in middle school and continue to apply the skills in other subjects. We wanted it to be free to give people an idea of what a Practice map is like.

Other maps are not free because it costs us money to make them, so the only way that we can continue to make more is if members subscribe.
