Quite Useful I use have a TI Nspire CX CAS, a TI 89 Platinum and a handful of high-end Android calculators. But when it comes to linear algebra (only), you can't beat this little app. It pretty much does everything you need to do. What I like most about the app is that with one key you can get a whole lot of information about a matrix in one place, and it even shows you the step-by-step operations for some of the routines. The only thing missions is the matrix template style interface for entering numbers.

Chris Brav

Almost useless Want to do simple matrix arithmetic on tablet. Wolfram's app almost useless. Must be online and doesn't seem to handle even simple sequences of operations. Only one at a time.

Giannis Dimaridis

Needs way more EDIT: Changing my rating from 4 to 3... It proved to be really useless since the day I bought it. I always find myself using the Wolfram Alpha desktop website instead of mobile apps, simply because it's way faster to operate. This app lacks significant features.

## Linear Algebra Trove (Free)

[This is a free version of Linear Algebra Trove]

Linear Algebra is a critical part of mathematics. You need to get it right!

Being successful at first-year university mathematics (or final-year secondary level), requires a lot of practice.

It also helps to recognize that there are patterns that repeat themselves over and over in the kind of problems that you encounter at this level.

This app helps in these areas. You are given a large collection of typical Linear Algebra example problems. The problems are logically grouped by topic, and are interspersed with definitions and theorems, using wording that is as simple as possible to get the ideas across.

Full solutions are given for each problem, and in many places, when you would like to see more detail about how a part of the solution was obtained, all you have to do is expand that sub-problem to see the steps that were used.

## Math Algebra Solver Calculator

## DragonBox Algebra 5+

DragonBox Algebra 5+ - The game that secretly teaches algebra

DragonBox Algebra 5+ Is perfect for giving young children a head start in mathematics and algebra. Children as young as five can easily begin to grasp the basic processes involved in solving linear equations without even realising that they are learning. The game is intuitive, engaging and fun, allowing anyone to learn the basics of algebra at his or her own pace.

DragonBox Algebra 5+ covers the following algebraic concepts:

* Addition

* Division

* Multiplication

Suitable from age five and up, DragonBox Algebra 5+ gives young learners the opportunity to get familiar with the basics of equation solving.

DragonBox uses a novel pedagogical method based on discovery and experimentation. Players learn how to solve equations in a playful and colorfull game environment where they are encouraged to experiment and be creative. By manipulating cards and trying to isolate the DragonBox on one side of the game board, the player gradually learns the operations required to isolate X on one side of an equation. Little by little, the cards are replaced with numbers and variables, revealing the addition, division and multiplication operators the player has been learning throughout the game.

Playing does not require supervision, although parents can assist them in transferring learned skills into pen and paper equation solving. It is a great game for parents to play with their kids and can even give them an opportunity to freshen up their own math skills.

DragonBox was developed by former math teacher Jean-Baptiste Huynh and has been heralded as a perfect example of game-based learning. As a result, it is currently forming the basis of an extensive research project by the Center For Game Science at the University of Washington.

Features

* 10 progressive chapters (5 learning, 5 training)

* 200 puzzles

* Learn to solve equations involving addition, subtraction, division and multiplication

* Multiple profiles

* Dedicated graphics and music for each chapter

* supported languages: English, français, norsk, svenska, dansk, español, 한국어, italiano, português, Deutsch, русский, 简体中文, 繁體中文, suomi, Nederlands, Eesti, Euskara, Türkçe, Čeština, Lietuvių, Magyar, 日本語...

## DragonBox Algebra 12+

DragonBox Algebra 12+ is a must-have tool for students so they can earn better grades and gain confidence in algebra and mathematics. It is based on the award winning game DragonBox Algebra 5+ but covers more advanced topics in mathematics and algebra:

* Parentheses

* Positive and Negative signs

* Addition of Fractions (Common Denominators)

* Collection of Like Terms

* Factorization

* Substitution

DragonBox Algebra 12+ gives players a greater understanding of what mathematics is all about: objects and the relationships between objects.

This educational game targets children from the ages of 12 to 17 but children (or adults) of all ages can enjoy it. Playing doesn’t require supervision, although parents can enjoy playing along with their children and maybe even freshen up their own math skills.

DragonBox Algebra 12+ introduces all these elements in a playful and colorful world appealing to all ages.

The player learns at his/her own pace by experimenting with rules that are introduced gradually. Progress is illustrated with the birth and growth of a dragon for each new chapter.

Dr. Patrick Marchal, Ph.D. in cognitive science, and Jean-Baptiste Huynh, a high school teacher, created DragonBox Algebra 12+ as an intuitive, interative and efficient way to learn algebra.

DragonBox Algebra 12+ is based on a novel pedagogical method developed in Norway that focuses on discovery and experimentation. Players receive instant feedback which differs from the traditional classroom setting where students can wait weeks for feedback. DragonBox Algebra 12+ creates an environment for kids where they can learn, enjoy and appreciate math.

Our previous educational game, DragonBox Algebra 5+ has received many distinctions including the Gold Medal of the 2012 Serious Play Award (USA), the Best Serious game at Bilbao´s Fun and Serious Game Festival and the Best Serious Game at the 2013 International Mobile Gaming Awards. It is also recommended by Common Sense Media where it won the Learn ON award.

Features

* 20 progressive chapters (10 learning, 10 training)

* 357 puzzles

* Basic algebraic rules with which the child can experiment

* A focus on minimal instruction encourages creativity and experimentation from the player
