Welcome to BRAIN Academy !
I am sure you are worried about your exams or maybe just want to learn the subject because you like it.
Mostly, the videos are based on SEE syllabus especially of Class 10 (the new syllabus by CDC for Compulsory Mathematics) and some of Class 9 of Nepal and some are based on CBSE syllabus. I am just a simple admirer of Mathematics, sharing whatever ideas that I have on Mathematics and Science. I hope you have fun exploring the channel.
Feel free if you have confusions or question suggestions to message us in the (comments) box.
Share it with your friends who might benefit from the videos.
Cheers!

NCERT Polynomials Ex.2.2 all solutions | Chapter 2 | CBSE | Class 9
Hello everyone!
This is a step-by-step explanation to the solutions of all of the problems of second exercise 2.2 of the second chapter polynomials of Class 9 of NCERT Maths Book. In this exercise, we discuss about values of polynomials at different values of variables such as x, a, t, etc. After that we talk about zeroes of polynomials; how to identify and find zeroes of different polynomials given in the question.
I hope this video was helpful to you.
If you have any confusion feel free to let us know in the comments.

Class 9 Ex:1.3.RECURRING DECIMALS INTO FRACTIONS (NON-TERMINATING ONES!) |NCERT Maths|CBSE
Просмотров 949 месяцев назад
Hello everyone! This one is about converting non-terminating recurring decimal expansions into fractions. We just need to know a few tricks to solve these types of questions. The first one is assuming the given number as some random variable such as "x" then we multiply the variable with powers of 10 depending on the number of digits that are recurring in the given question. And finally subtrac...

Hello everyone! In this video, we will be converting the given fractions into decimal forms and then also determine what type of decimal expansion each of them have. There are three types of decimal expansions. They are terminating, recurring non-terminating and non-recurring non terminating. In the first part of the video, we talk about these three types of decimal expansions. And since ration...
Class 9 Ex:1.1.Find rational numbers between two numbers |NCERT Maths|CBSE
Просмотров 939 месяцев назад
Hello everyone! We are solving some questions about number systems in maths. Here, we talk about what is a rational number, is zero a rational number; if so why it is a rational number, and can it be written in the form of p/q? Similarly, we try to find rational numbers between numbers and fractions in two different ways. The first method is more of an intuition type and the second one is more ...
HOW TO FIND MODE (EASY) | INDIVIDUAL, DISCRETE AND CONTINUOUS SERIES | STATISTICS
Просмотров 809 месяцев назад
#seemath #mathspreparation #exampreparation Hello everyone! Mode is one of the easiest topics in statistics. Here, we find the mode of three types of data; individual, discrete, and continuous data. Mode is the item that repeats the most in a data set. In the individual and discrete data, it is a one-step solution whereas in the continuous data, you do have to use a formula but the formula is e...

Thanks!
Sir i dont think you are from India . Where are you from ? But amazing explanation
Thanks! From 🇳🇵 Nepal.
Did you get the trick?
Thanks your explanation is so understandable..
Welcome!!!
Can you solve it by yourself now🙃?
Would've really helped if you also showed a couple of questions from QPs which need/use these formulas.
Sir aap hindi bola kro jada views ayee gaa video per you try 1 time and then you found to improve really 💯💯🌟
Thank you for your suggestion, lekin mujhe Hindi sirf thoda thoda hi aata hai!😅😅

Thank u sir
Where is the proof of this relations??
Thank you so much sir 🥰🥰
You're welcome! 😃😃😃
Great job sir ji thank you so much
You are most welcome!
Can you identify rational and irrational numbers now?
Can you still remember all these formulae???😅
Can you simplify the expressions now, give it a try!
Isn't it easy to convert fractions into decimals, let us know in the comments.
Can you find rational numbers between any two numbers now? What about between 5 and 6? Let us know in the comments.
Can you convert the decimals into fractions now? Let us know in the comments below.
Can you rationalize the denominators now? Let us know in the comments.😅

Put this into 1.25x...:-)
Welled explanation sir..i can't imagine that this is very easy.😢❤.. tomorrow is my physics exam... and I am doing this from two three hours but I can't do this from this video in Once Time I done it❤ ☺️ thanxxx a lots sirr..❤
I am so glad it helped. Best of luck for your examination👍👍👍!!!
Why do we assume gravity is the same as acceleration? In formula F=m*g. F= MA
Gravity is not same as acceleration, gravity is a force but sometimes people just call "acceleration" as "gravity" for 'acceleration due to gravity' since the acceleration is produced by force of gravity.
@@brainacademy100 thank you
Thank you sir
Glad I could help!!!
its wrong BCOZ newton law of gravitation is wrong
How?
