Very useful It helps me a lot with my pre-cal work and it is amazing high- five to the developers

Leo K

Impressive Works, doesn't even ask for Internet access, or the rest of those annoying permissions...

Mikhail Volkovin

Amazing I have intense respect for this developer. Good interface, great how it gives the work. Love it.

Pavel Sedach

Ads Is there a way I can pay you to turn the ads off? Please make a paid version - I'd be willing to give a buck or two.

Samuel Silver

Can't use scientific notation Worthless for anything other than simple quadratic equations. Useless in science class. Can't use really big or really small numbers.

Gabe Bauza

??? Do you think you can make it step by step so you can actually see how a student would show his work?

Finally an app that can solve for all types of equations and isn't just limited to a formula!

Equation Solver is an app that can solve for one variable in any equation, it is extremely versatile and a must for anyone in school or anyone that deals with equations on a daily basis.

Please note all variables must be lowercase!

Functions supported:

+, -, *, /, ^ (exponent), sin, cos, tan, asin, acos, atan, sqrt (square root), abs (absolute value), ln, log

Instead of depending on hard coded formulas, Equation Solver finds the answer through a brute force method. This allows the app to solve for all sorts of problems in a relatively short amount of time!

Please email me at alagoapps@gmail.com if you have any questions/concerns or bugs. Please attempt to contact me before leaving a bad rating to see if I can help.

Known Issues

- None at this time

Permissions

- Internet is only needed for the advertisement, NOTHING else. This app does not rely on an internet connection to solve equations and can function offline.

Quadratic Calculator accurately solves ANY standard form quadratic equation. It gives decimal and simplified fractional answers. It even SHOWS WORK step-by-step. Since the app uses this process, I can almost guarantee it has 100% accuracy. It has been tested on dozens of simple, complex, and varied equations, all of them being solved flawlessly.

The app uses the 3 coefficients of ANY standard form quadratic equation and solves the equation step-by-step. It simplifies, takes out i's, gives simple AND complex root answers, gives fractional answers and decimal answers, and just about any other kind of answer that you could use.

This app is perfect for any student that is taking an algebra course, because it will make most equations easier. This app calculates the answer in less than a second, and even shows you how it got to it.

This is simply the best quadratic equation solver for not only Android devices, but even the expensive ($2+) iDevice quadratic solvers can't compete with all the features in this app.

Features:

- Solves ALL standard form quadratic equations. Simple or Complex roots.

- Gives ACCURATE, and Practical answers, not just 2 large decimals.

- SHOWS WORK. It shows you how it solved the equation step-by-step.

- In-app instructions.

- Works all offline.

## Calcularis Scientific Calc

Calcularis: The only scientific calculator you will ever need.

A history feature will allow you to save as many equations as you need and allow you to retrieve them when needed or edit them. No need to press the = button because Calcularis is always calculating.

The full equation with multiple lines makes it easy to keep track of what your are calculating. All the standard scientific functions are on visible keys. There is a scientific and engineering notation mode as well.

Simply the the best free scientific calculator on the market.

The paid mode has the following additional features:

* applications such as Tip and split calculator, Loan calculator, math equations like quadratic equation.

* large set of constants

* unit conversions

* more functions accessed from the FN button

* more key layouts such as a 10 Key and Programmer/logical calculator accessed from the KEYS button

During the trial period (two weeks), you can use the features of the paid mode to try them out. After the trial period, the main features of the calculator will continue to work and will remain free.

Move over RealCalc, the new #1 Android scientific calculator has arrived. Some have asked the question whether you still need your TI, HP, Casio or Sharp calculators. The answer is yes. Phones are not usually allowed in the classroom or in testing centers. You will always need your old calculator for that. Plus calculators like TI-83, TI-84, TI-89 and TI-Nspire include graphing capability that is not currently supported.
