Binomial theorem and Quiz

Opening the app for the first time

The moment Binomial theorem and Quiz loads, you're presented with a clean interface. The home screen shows a list of topics: Pascal's triangle, factorial notation, combinations, the binomial theorem, term independent of x, and binomial theorem for any index. There's no tutorial overlay, no forced walkthrough. You just select a topic and start reading. The notes are crisp and clear, with both dark and light modes available. The text is easy to read, and the explanations are simplified with extra side notes for further clarification. Each chapter contains over 30 examples with step-by-step working. At the end of each chapter, there are past paper examination questions. The app also includes a guided math quiz with 10 levels. The bottom navigation bar is simple: Notes, Quiz, and More. The Notes tab is where you spend most of your time reading and learning. The Quiz tab is where you test your knowledge. The More tab contains settings, about, and other options. The app asks for no permissions – it doesn't request access to your camera, location, or storage. This is a privacy win. The entire onboarding takes about a minute. You just pick a topic and start learning. The app feels lightweight – it's only 6.7 MB. It runs on Android 6.0 and above. The developer, Multimedia E-Learning Education System (MELES), has created a series of pure math apps, including Algebra 1 Pure Math, Trigonometry 1 Pure Math, and Integration Notes & Quiz. This app is part of that series. The version history shows regular updates – version 1.0 was released in August 2019, version 2.0 in November 2020, version 4.0 in September 2021, and the latest version 5.3 was released in October 2025. The latest update introduced a new 10-level math quiz, a new dark mode, and optimization for Android 16.

When notes meet the quiz

Here's where the app shows a workflow that isn't obvious from the Play Store description. The note-taking section and the quiz section are designed to work together, but not in the way you'd expect. You study the notes first, then you take the quiz. The quiz has 10 levels, each with increasing difficulty. The questions are based on the topics covered in the notes. If you get a question wrong, you can review the notes to understand the correct answer. This creates a loop: study, test, review, and repeat. The app doesn't automatically track your progress or suggest which topics you need to review. You have to manage that yourself. However, the structure is clear: you read the notes, you take the quiz, and you check your answers. The past paper questions at the end of each chapter provide additional practice. This workflow is particularly useful for students preparing for exams. They can study the notes, test themselves with the quiz, and then practice with past papers. The app doesn't provide feedback on incorrect answers – it just tells you if you're right or wrong. This is a limitation, but it also encourages you to go back and review the notes. The coin system, mentioned in one user review, suggests there may be a gamification element, but it's not clearly explained in the app description. The combination of notes, quiz, and past papers creates a complete study package for the binomial theorem.

How the app performs day to day

In daily use, Binomial theorem and Quiz is reliable. The app is small and lightweight, so it loads quickly. The notes are displayed clearly, and the dark mode is a nice touch for studying at night. The quiz works smoothly – questions load quickly, and the interface is responsive. The app has a 4.6 rating on Google Play, based on 21 reviews. However, there are some concerns about the authenticity of the reviews. AppRecs reports a 47% review manipulation risk, meaning some review patterns appear unusual. Additionally, 48% of sampled 5-star reviews are very short, which could indicate fake reviews. This is a red flag. One user commented "Coins.... boring," suggesting the in-app coin system may not be engaging. Another user asked "Is this binomial expansion," indicating confusion about the content. These are minor issues, but they suggest the app could benefit from clearer explanations and a more engaging quiz experience. The app does not contain ads, which is a plus. It's completely free, with no in-app purchases. The app's data safety section states that data is encrypted in transit, but data cannot be deleted. This is a privacy concern for some users. The app also shares data with third parties, including app activity, app information, and device IDs. This is something to be aware of. The app's performance is stable – no crashes or bugs reported. The latest update optimized the app for Android 16, ensuring compatibility with the latest operating system.

Permissions, pricing, and technical details worth knowing

The app requests no permissions. This is unusual for a modern app, but it's a positive – it means the app doesn't access your camera, location, contacts, or storage. The app size is 6.7 MB, making it one of the smallest educational apps available. The app is free and does not contain in-app purchases. The app is available on Android 6.0 and above. The app is not available on iOS – there is no version for iPhone or iPad. The app is part of a series of pure math apps by Multimedia E-Learning Education System (MELES). Other apps in the series include Algebra 1 Pure Math, Trigonometry 1 Pure Math, and Integration Notes & Quiz. The app's version history shows regular updates – version 1.0 was released in August 2019, version 2.0 in November 2020, version 4.0 in September 2021, and version 5.3 in October 2025. The latest update introduced a new 10-level math quiz, a new dark mode, and optimization for Android 16. The app's security scan on APKPure shows 0/57 security vendors flagged the file as malicious. The app is safe to download and use. The app's data safety section states that data is encrypted in transit, but data cannot be deleted. The app shares data with third parties, including app activity, app information, and device IDs. The app's coin system, mentioned in a user review, suggests there may be a gamification element, but it's not clearly explained. The app's core functionality – providing notes, a quiz, and past papers on the binomial theorem – is well-executed. The app is a useful tool for students studying the binomial theorem, whether for A-Level, JEE, or other exams.
