The purpose of this calculator is to help you solve algebraic equations. If you have a math expression that you need to calculate, this app will let you do that in a few seconds. 

For example, if you have an expression like 2x+3y-4=0, you can simply enter the values x, y, and 4, and the result will be 8. If you want to try another one, just change the values and you will get another answer, 8. This app is very useful for those students who have to solve a lot of equations in their homework or exam. 

There are two modes in this calculator. One is the standard mode, where you can simply enter the values and get the answer. The other is the demo mode, where you need to restart the app every 10 times before getting the answer.
