Best calculator I've ever encountered First the bad: no option for different number bases such as binary or hexadecimal, few statistics functions, and no numerical integration  as far as I've discovered! Now the good: Almost every facility you can think of from factorising quadratic expressions to solving pentics (?), from raising numbers to complex powers to graphs in both cartesian and polar coordinates. It can mix radians and degrees in the same calculation. An astonishingly versatile app. Moreover it has 3 calculator work spaces and 3 graphic work spaces so you can keep earlier work to refer to later. P.S. It can also add 2 and 3!
Ze Junior
This is the one! Stop searching for an algebra and graph calculator. I have already tried almost all calculators on Google Play. Nothing comes even close. Almost perfect. Two things I missed: digit grouping (1,000,000,000); and the option to define the number of digits after decimal.
David LeClear
Awesome! One cool thing I like is that it will simplify equations for you. It also has many other cool things it can do. I used it for my calculus II class being able to do everything that I needed it to do.
James Miles
Engineering Mode Great calculator! Glad this feature was added... This is now the perfect calc app!

Best calculator + app available, period. I have tried dozens, and this one is easily the best. Does a nice job of balancing the complexity of its features with ease of use, simplicity, and speed. Love the way it automatically displays results (answers) in multiple forms, including proper and improper rational forms (if possible). Love the multiline display. Will easily do permutations, combinations, trig, graphing, tables, etc. You won't regret getting this app.
Excellent work on the app Could use an information guide or user instruction on how to use of the stuff like how to type in a 4th root.. rt4
Mathlab Apps, LLC March 16, 2014
For example, type: root4(256).
Or look at the video 2'00": http://youtu.be/doIYR6hUCpg I would not have been able to get the good grade I did without it Little confusing to a math novice at first, but great when you figure it out
Mathlab Apps, LLC March 19, 2014
Here is a video review about how it works: http://youtu.be/doIYR6hUCpg For all math people Very convenient app; I use it over my regular handheld calculators all the time. My only suggestion would be a way to duplicate very long expressions right in the workspace if I don't want to add it to the library. Otherwise an excellent app!

Even for the unlikely case you forgot to insert a memory card it will also function without it using internal area. If you intend a simple scalar use, please get Advanced Calculator (if requiring special definition such as Pascal's Triangle) or set x to [number, number] for simpler mathematical systems.
The app also creates the graph fast, your graph files will be in /graphs/graph.html and same other file with the extension .png The is in fact not random but always on the increase as time goes by so each file is stamped with time as its filename and a greater number equals newer plotting.

It fully emulates TI84+, TI84+ Silver Edition, TI83+, TI83+ Silver Edition, TI73, TI83, TI85, TI86, TI82, and TI81 calculators made by Texas Instruments. And yes, if you have got a tablet, it will become a really BIG TI calculator. AlmostTI also lets you save your calculations at any point and then select from several previously saved tasks.
To run AlmostTI, you will need at least one calculator system ROM. AlmostTI does not include any calculator ROMs on its own, as they are intellectual property of Texas Instruments. You should place your own ROM, preferably dumped from the calculator you own, onto your internal storage. AlmostTI recognizes following ROM files (in upper or lower case):
TI85.ROM, TI86.ROM, TI81.ROM, TI82.ROM, TI73.ROM, TI83.ROM, TI83P.ROM, TI83SE.ROM, TI84P.ROM, TI84SE.ROM

Listen Read Device Only Added Installed A Scientific calculator is a type of ecalculator, usually but
not always handheld, designed to calculate problems in science,
engineering, and mathematics. They have almost completely
replaced slide rules in almost all traditional applications, and
are widely used in both education and professional settings.
In the Modern scientific calculators generally have many more
features than a standard four or fivefunction calculator, and
the feature set differs between manufacturers and models;
however, the defining features of a scientific calculator include
as fallowing bellow:
**Engineering Mathematics.
**Engineering Science.
**Engineering Mechanics.
**Scientific notation.
**Scientific Calculations.
**floating point arithmetic
**logarithmic functions, using both base 10 and base e
**trigonometric functions (some including hyperbolic
trigonometry)
**exponential functions and roots beyond the square root
**quick access to constants such as pi and e
**In addition, highend scientific calculators will include:
**hexadecimal, binary, and octal calculations, including basic
Boolean math
**complex numbers
**Complex fractions
**statistics and probability calculations and also in Dynamics
Mathematics.
**calculus
**conversion of units
**physical constants
A few have multilingual displays, with some recent models from
HewlettPackard, Texas Instruments, Casio, Sharp, and Canon using
dot matrix displays similar to those found on graphing
calculators.
Attention PleaseDear users We have try to make it most
accurate as well as we can make,but in a certain point or
condition if you got/face any error/inaccuracy then fell free to
