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!

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.

It works. Inputting values with exponents is cumbersome and not entirely intuitive. That being said, I did figure it out and was able to finish writing the homework assignment for tomorrow.

Maria Rodriguez

All right.... Well you can only do equations on here and I'm not sure if the answers are even right.

mark parsons

Very good but Will solve for any variable in an equation but I would have liked to see the re-arranged equation that it used. For V=IR you can ask to solve for R. It will prompt for the values of V & I then give the answer. I would have likedalso to see the equation the app used ie R=V/I.

Kareem McClam

Best Ever This really helps when i have h/w for math class I would give a five but everything needs improvement

WhatThe Fuska

Not quite there There's no option that I can see at least that allows exponents or square roots etc. If that were to implemented this soon would be perfect

lollipopyx

Add graph function maybe? It's a really good way to double check my answers and all but would be better if a graph function was added. :)

Xavier Hains

App made in heaven Thank you! You don't know how much time I saved. Before I got this, I thought it was going to take me an hour or so to finish my math homework and now it took 7 minutes to finish 20 questions of two-step equations. That I thank you for.

Sheng Hong Pang

Nice app└(^o^)┘ It solves quadratic equation very well, and I can check my answer with this app. Moreover, the size of the app is smaller than others.

Nigel Pounder

Good work works well for me. Would be even better if you could build a libary

Chris Grim

Doesent work with numbers to a negative power for example if u put in 2^-2 wanting to to the power of- 2 it takes it as 2^1-2 because it has no variation between negative or minus symbols

opal mines

Division There's no division? And all of my problems are written like a fraction of sorts, there's no option for that either

KARLA VANESSA

Amazing My teacher is giving this and he let us use calculator but... yeah he don't know I'm using this calculator ~~~ Thanks T__T

Tom Fitzsimmons

Easy to enter quite complex equations but most of the time answer is "illegal variable" so have to proceed to solve myself - defeats the purpose of the app!

Steve McCollum

Good as far as it goes... Would like a factorial function to make certain probability calcs possible.

Carter Peterson

Great app It does just leave sometimes but all you have to do is reopen it

shivang rathode

Not working properly I have to solve linear equation in one variable but this is showing wrong answer

lexi love

Thanks Thank u so much this helps me all the time love it

John Perez

...! This is the best app ever, I needed it to solve those problems I had a hard time with. I wish I could give it 6 stars

jackie ling

It was working great when I first download this app. Now i'm using it again and it will solve my equation.

Hannah Weizenegger

Question.., Is there an option for fractions? Because I just put the / sign so plzzz tell me if I'm wrong.

Evelyne Cooper

It's okay It helps alot, it will be better if u add factions and negative signs too. Thank you.

Niels Saavedra Tapia

Excellent very good app, but seems that you don't have euler constant or exponential function (e=2.72...)

Imrish Ken

Disappointed I thought it would show the work but turns out it doesn't

RexpertheKinG Nuttin

Pretty good but... This app is great at solving equations if you know how set it up but I would like to see the equation being solved.Other then that this app is great

moustafa saad siddiqui

Its good but please add a multiplication and division sign

Josh Lenon

Works great Would give 5stars if it showed the steps

Hurree Brookline

It is really bad(example numbers like 23-15 )it can t solve :(:(:(

Stampy Jr

Best way to do algebra Whooooooooooooooooop Yeah!

George Grund

Good app Some problems with Logarithmic equations, but its not incorect

Pranay Sajdeh

Great Solves equations pretty well it seems :)

Rohan Amberkar

Algebra Need a way to solve for x in terms of another variable

TEO AGULAR

Get it It helps you with the hw get its free and it works

Rupam Bhattacharya

Good one Can it have a feature of showing how to solve the problems? Please

tasmiya iqbal

Its ok Doesn't have the squared button...!!?

suvranil dutta

The Perfect Woooow it's fantastic... Just what a great mathematical program u did... It is a great help for me.. Thank you very much...

Nauman Tariq

Math Tools A must have application for teachers

Genet Geleta

Not downloading Does not download please fix

Mark Landis

Equation solver Just needs to add < >

Dakavin Pannell

Thanks I don't care if i get wrong answer

Sachin Pandit

Good one.. Given 5 stars to appropriate efforts.. Putting number in equation lil clumsy. GuI can be improved

Kyle Elzinga

Great app.,Especially for a free app.. No ads

Benidck Barsomo

Differential Equation Not Supported I cant solve some problems in D.E (e.g xy*dx-(x^2+2y^2)*dy=0) please let me know how it works , if ever .

Desmond Thang

Great app It's great for basic equations, which is what I do. I'm not too good at equations and love to use this app to help double check my answers.

Tom Polk

This works well for me. I've looked for years for an app that would let me type in an equation with multiple variables like I could with Solver on my 20-year-old HP 95-LX palmtop computer. This is the first app I've found that does exactly that. I reserve five stars for perfect apps, so my four star rating is excellent. What makes this not perfect for me is that it's not as intuitive and as fast as the tiny executable in the HP 95-LX. HP's old Solver runs blistering fast on a 5 MHz 8088 processor, allows for multiple character variables and uppercase, has a nice running list of multiple equations, and is generally more intuitive. Beats me why no one has been able to come up with something as elegant twenty years later, but this Equation Solver comes pretty close.

deva yekula

Just good Yeah it solves simple equation's but not compound and it takes lots of time to show the answer but it done very well you can dwnld ds . and u have to change bound for large answers

Kamryn Johanns

Amazing When ever I need help on my algebra homework this app can solve it all!

Robin Henkle

Too basic Only good for equations that have integer answers- otherwise it just estimates the answer, not very mathematical

Mike Lins

No square roots! If there are no square roots or indexes, then what makes this app different from the stock Android calculator?

Mark Ortega

Not sure I'm not sure if it is giving me the right answers to multi step equations with distributive property

Macaulay Hamp

Good but should make it so u can see how the question is worked out

suharyanto 1269

Useful Help me to calculations some mathematics formula which i use everyday :)

Paolo Vila

Yo u cantor donde fractions It is a great application an really simple to use but you cannot solve fractional ecuations with it

Kate Sanchez

Love it I have no more trouble of doing my HW no more

Kavon Jones

Best app ever!!!!!!!!! This app did all the equations I typed in and when I checked them my self they were all right this app saves so much time.

longinus overman

Pretty good app I would've given this a 3 star rating but apparently, the competition is not so stiff among the free calculator market. Downside: it only answers questions within -100 to 100. Upside: it doesn't crash like the other 5, supposedly superior, apps I loaded and erased

Venessa Emmanuel

Needs upgrade No bad but i cannot seem to find to work inequalities with < andandsigns.

Jonathan Clarke

Haha Doesn't show steps. This is worthless. Who the hell wants knowledge without understanding

Edgar Ruiz

Its a good app I use it to double check my work there is still a couple equations it won't answer but other than that this app is great it helps me do my math homework

Alahna Bennett

Aaaaahhhh Where is the divided by sign?I wil rate 5 stars if someone tells me. Or algo could tell me.

rishi dhawan

Complex roots The calculator doesnt give results of eqns which involves complex roots ... Fix this and I would give 5★

Shafiq Ayach

Good Extremely useful we study equations at high school and it helps me to check after words have I done any mistakes keep up the good work!!!

Katie Marie

Thrilled Can't believe I found this app. Homework struggles=GONE.

Patrice Andamo

Necessity This app is just what I need. Kinda hard to input stuff but it works.

Kamal Mahmoud

I disliked it It's so bad. It doesn't give answers more than 100000. It's so slow for large numbers.

Wajeeh Ul Hassan

Normal Normal but it doesn't shows the whole procedure some times but it is time saving.

Somesh Sharma

Now it's become very buggy It crashes all the time for quadratic equations

Qiushi Liang

Its good but.. Its good app and its helpful. However sometimes it just can not solve equation with a extremely small number. For example the acidity, 1E-14. Its just can not solve it.

Mina Gram

I LOVE THIS APP!!! I take forever with math but always second guess myself and I never want to back track my work this app is perfect!!!
