Not all people are a fan of math. Even engineering student will sometimes dislike their mathematics major topic. In connection with it, I'm here happy to share this to all of you this news of mine about an open source android app which already been available publicly in playstore and help so many students already who are struggling in their mathematics homework.

To utilize our learning, I bring here a tutorial how to solve a Matrix data using my newly found android open source app which can save our homework struggle.

This tutorial will not encourage students to be dependent in this open source android app but to use the app in a way that can help to nurture their knowledge more in numbers.

Introducing NCalc+ an open source android app which is developed by Le Duy Tran. This is an open source project in Github, click this [link](https://github.com/tranleduy2000/ncalc) to visit about the open source project.

Since, this article is made to tutor how to solve Matrix equation and problem, then without wasting time anymore, be sure to visit the app in playstore and download it in [here](https://play.google.com/store/apps/details?id=com.duy.calculator.free).

To solve any Martix equation and problem, be sure to download and lunch the app.

Lunching the app will directly bring you to scientific version of the calculator as seen in above photo. The scientific calculator is commonly the type of calculator in engineering study.

#### Step 01:

Input the matrix equation you want to solve. The app can solve up to infinite matrix. But the features directly display 3x3 after opening. But you can change the matrix number by creating it. Simply click the **"CREATE"** button and fill the **"columns"** and **"rows"** required. 
Be sure to provide the necessary input. The the **Matrix A** is for the 1st data and **Matrix B** for the 2nd data.

**The data I try to input in 3x3 matrix:**
