Best matrix app With free step by step solutions this app is very useful for solving and learning matrix and vector operations. Cool new interface too.

John Miguel Molina

Finally I found a creator that reply to our feedback. I will recommend it to all of my classmates. Keep it up.

Enrique Ceballos

Awesome Great overall. I am a math professor and I recommend this app to my students one we get into large matrices or into situations where we have to put a matrix to a large power. The only suggestion I would give to the developer is to eliminate what's in a cell when one chooses it. It takes time to have to clear the cell instead of just typing the number in

Marilyn Cross

Algrebra This looks and sounds excellent, how long will this last in order to learn the concepts and rules?

A Google User

Decision made I haven't use this app a lot but for the short time I have, its been doing well til this pass week. It keep force closing on me. If it keeps up.....can we say uninstalled. (Update 2/4/14): time has passed since my last statement. I must say there has been a lot of improvement and I do like the sleeker look it has. I have used this app a lot and it has proven to be very useful. Thank you for fixing the bugs that was causing it to force close!

Thank you for your review, Brittney! ComfyMobile December 11, 2013

Dear Sebastian! If you want to fast closing, you have HOME button on your device. Shows steps I accidentally reduced my B matrix too far, and it erased a row in A, mostly: having to clear wrong data from each segment before entering correct #'s is a pain. Besides not preserving the column data and this extra step it's a gem for checking work.

ComfyMobile October 6, 2013

This feature is made to prevent data loss in case of accidental resizing. We plan to add quick removal, thank you for your review Can't even get a determinant right Kept telling me the determinant of a matrix was 4 when more reliable software and my own calculations confirmed it was 1. Piece of junk.

ComfyMobile October 22, 2013

Thanks for your review. Can you sending me your matrix? comfymobile@gmail.com # What's New

## 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.

## Graphing Calculator by Mathlab

If you're looking for a graphing calculator app that works smoothly and seamlessly, you've found it! Graphing Calculator by Mathlab is a scientific graphing calculator integrated with algebra and is an indispensable mathematical tool for students in elementary school to those in college or graduate school, or just anyone who needs more than what a basic calculator offers. It is designed to replace bulky and costly handheld graphing calculators and works on virtually any Android phone or tablet.

Furthermore, Graphing Calculator by Mathlab displays calculations as it performs them on the high-quality display of the Android device, making it easier for the user to understand the calculations and see them clearly. This app has two great strengths. First, it acts as a fine scientific calculator, but, more than that, it displays the intermediate steps of the calculations as you type. It allows the students to both watch and learn how the calculations are made and how to find the final answer. Second, the graphing ability is absolutely stunning! Not only does the calculator beautifully display the graphs, but it automatically generates the x- and y- values and displays them as well.

The original Hands-On Equations program, using physical game pieces, has already helped more than a million students gain confidence with algebra. Now that same, proven method is available virtually in the palm of your hand__ for FREE!

A short, helpful introductory video by Dr. Borenson, the inventor of Hands-On Equations, assures and encourages young students that algebra is fun and easy to master.

This FREE app gives students a taste of the same in-depth algebraic experience they will have with the paid version of Hands-On Equations 1.

This is how the App works:-

•The unknown X is represented by a blue pawn on the Android screen while the constants are represented by number cubes.

•In Lesson 1 the icons do not move. The student uses thinking or guess and check to solve the equations.

•Beginning with Lesson 2, the student places the game pieces on the balance scale to represent the two sides of the equation.

•Beginning with Lesson 3, the student simplifies the equation by removing pawns from the balance to solve for the unknown X.

•The student verifies his/her solution by resetting the problem to conduct the check.

•Feedback is provided to the student in the check phase of the problem.

•Simple touch features are used to move the pieces around.

•An expert instructional video is included for each lesson.

•An intuitive user interface makes the app easy to use.

Hands-On Equations 1 Lite is perfect for introducing algebra to kids (or adults) in an entertaining and fun way. The app will boost their self-esteem and give them the confidence to take on even more complicated equations! Download this FREE app today and see how much fun and how easy algebra can be!
