Online Maths for free has been brought here for the ease of students so that they can get access to each and every fundamental concept and learn quickly. We have provided Maths learning materials for all the standards (Standard 1 to 12). Also, Maths questions with solutions are given for each concept to help the students understand better. Practice Maths here with the given examples and practice questions for all the Classes from 1 to 12. For better practice, worksheets are also provided by us, so that students can excel in the concepts.
In mapping Maths, we will come across many concepts. The origin or base of Maths is Counting, where we learned to count the objects that are visible to our eye. Mathematics are broadly classified into two groups: Pure Mathematics (number system, geometry, matrix, algebra, combinatorics, topology, calculus) and Applied Mathematics (Engineering, Chemistry, Physics, numerical analysis, etc).
Maths has a lot of formulas based on different concepts. These formulas can be memorized by practising questions based on them. Some problems can be solved quickly, using Maths tricks. Class 1 to 10 has been taught with the general mathematical concepts, but its level increases in Class 11 and 12.
We are providing learning materials for students of Class 6 to 12 based on the syllabus. In these classes, students set their foot into the world of all the important theories in Maths, like whole numbers, basic geometry, integers, decimals, algebra, ratio and proportion, etc. Since kids are more receptive to learning, when it is associated more with play than with work, hence it is a good idea for parents to expose kids to math in fun ways. We provide lessons for students till class 12, where they study the most complex topics like 3-D geometry, vector algebra, differential equations, matrices, etc. A few of the links of important topics have been shared here for your convenience.
With the help of animations and innovative ways of teaching by our experts, the ideas and concepts are sure to stay etched in your minds forever. The purpose is to make math fun and help kids grow to understand that math is fun. Instead of being afraid, the kids will then be excited about the subject for the rest of their educational journey. You can engage yourself with interactive video sessions, regular tests prepared by our experts and do continuous analysis based on your performance.
To become an expert in these basic concepts, students need to practise questions and solve worksheets based on them. There will few more basics such as multiples, factors, HCF and LCM, which will be introduced to the students in their secondary classes.
Frequently Asked QuestionsQ1 Why do we learn Maths? Maths is the foundation of all subjects and helps to improve brainpower. Our universe is made up of numbers. Maths has been at the centre of science, data handling, engineering, technology, space and research, and so on. Mathematics is important in everyday life. As a result, learning maths is required in order to observe and interpret the universe. Q2 Why is Maths so important?Mathematics provides structure to our life and reduces ambiguity. Learning Mathematics improves our reasoning power, creativity, abstract or spatial thinking, critical thinking, problem-solving abilities, and even effective communication skills. Q3 What are the different branches of maths?The major branches of maths are:
Fundamentals of Maths covers basic arithmetic operations or calculations such as addition, subtraction, multiplication and division, which are taught to us in primary classes. Going forward, in higher classes, students will learn basic concepts like algebra, geometry, factors, ratios, etc.
My goal is to study derived algebraic geometry, where derived schemes are built out of simplicial commutative rings rather than ordinary commutative rings as in algebraic geometry (there's also a variant using commutative ring spectra, which I don't know anything about). Anyways, since the category of simplicial rings form a model category, we can apply homotopy theoretic methods to study derived schemes.
I thought the first thing I should do is study simplicial homotopy theory, in order to learn about model categories and simplicial objects. So I started reading Simplicial Homotopy Theory by Goerss and Jardine. How should I study this book? There are very few exercises, unlike standard graduate textbooks like Hartshorne, and a lot of the proofs are simplex/diagram chasing, so I decided to skip a lot of the proofs and read the book casually.
A big disadvantage to this method is that I don't understand anything at a deep level and I'm only familiar with a few buzzwords. But I feel overwhelmed by the amount of prerequisite material I need to understand to learn DAG, because most of it is written in the language of $\infty$-categories. So what should I do? How can I get to "research level mathematics"?
I propose the following plan, assuming a basic background in scheme theory and algebraic topology. I assume that you are interested in derived algebraic geometry from the point of view of applications in algebraic geometry. (If you are interested in applications to topology, you should replace part 2) of the plan by Lurie's Higher algebra.) The plan is based on what worked best for myself, and it's certainly possible that you may prefer to jump into Higher Topos Theory as Yonatan suggested.
0) First of all, make sure you have a solid grounding in basic category theory. For this, read the first two chapters of the excellent lecture notes of Schapira. I would strongly recommend reading chapters 3 and 4 as well, but these can be skipped for now.
Then read about stable $\infty$-categories and symmetric monoidal $\infty$-categories in these notes from a mini-course by Cisinski. (By the way, these ones are in English and also summarize very briefly some of the material from the longer course notes). These notes are very brief, so you will have to supplement them with the notes of Joyal. It may also be helpful to have a look at the first chapter of Lurie's Higher algebra and the notes of Moritz Groth.
Read lecture 4 of part II of Moerdijk-Toen, Simplicial Methods for Operads and Algebraic Geometry together with section 3 of Lurie's thesis. Supplement this with section 2.2.2 of Toen-Vezzosi's HAG II, referring to chapter 1.2 when necessary. This material is at the heart of derived algebraic geometry: the cotangent complex, infinitesimal extensions, Postnikov towers of simplicial commutative rings, etc.
3) Before learning about derived stacks, I would strongly recommend working through these notes of Toen about classical algebraic stacks, from a homotopy theoretic perspective. There are also these notes of Preygel. This will make it a lot easier to understand what comes next.
4) Finally, read about derived stacks in lecture 5 of Moerdijk-Toen and section 5 of Lurie's thesis. Again, chapters 1.3, 1.4, and 2.2 of HAG II will be very helpful references. See also Gaitsgory's notes (he works with commutative connective dg-algebras instead of simplicial commutative rings, but this makes little difference). His notes on quasi-coherent sheaves in DAG are also very good.
In my opinion the best foundations to any modern topic in homotopy theory, and derived algebraic geometry in particular, is "Higher topos theory" of Lurie. The scope covers all the required ($\infty$-)categorical framework, and every chapter starts with a very conceptual motivation. In addition, the book also contains appendices which explain classical material (such as model categories) in a very readable way. You might find in the beginning some proofs which involve technical combinatorics of simplices. Don't be discouraged. Feeling comfortable with simplices is essential and this requires working out some details. The proofs in the book do become increasingly conceptual with each chapter, as the concepts themselves get built and acquire depth.
I'm going to take a dissenting view, here. I think the best way to assimilate concepts in derived algebraic geometry (for finite fields, $\mathbbR$ or $\mathbbC$), is to understand where and why they are used. Then, work backwards when the need arises. Personally, I found it formidable to read through any section of Toen-Vezzosi's homotopical algebraic geometry series straight through. I'd first recommend reading and understanding the content of Vezzosi's AMS notice, here: Once you begin digesting the need for replacing the source category for Grothendieck's functor of points approach to algebraic geometry with derived commutative algebras, browse through the literature and find instances where this becomes necessary. From my perspective, the most striking application is here: , where one sees (sloppily speaking here), that even replacing the source category with truncated derived objects goes a very long way in recovering classical results. Feel free to let me know if you'd like me to explicate further.
The files below contain notes for various parts of the A-level Mathematics and Further Mathematics specifications. They are mainly short(ish) notes with occasional examples, but also contain links to relevant NRICH and Underground Mathematics problems.
Underground Mathematics is hosted by Cambridge Mathematics. The project was originally funded by a grant from the UK Department for Education to provide free web-based resources that support the teaching and learning of post-16 mathematics.
These are full notes for all the advanced (graduate-level) courses I have taught since1986. Some of the notes give complete proofs (Group Theory,Fields and Galois Theory, Algebraic Number Theory, Class Field Theory,Algebraic Geometry), while others are more in the nature of introductoryoverviews to a topic. They have all been heavily revised from the originals. I am (slowly) in the process of producing final versions of them and publishing them.Please continue to send me corrections (especially significant mathematical corrections) and suggestions for improvements.
