# Description

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.

Its nice, i have problem in typing exponentials, and when the equation is complex,many operations done on a single variable,the result is wrong or not shown. I think it should have a box which shows the complex equations written,just as we write it by hand. Also can we somehow get answer of variables in terms of an unknown constant , like solving x^2 + x + a =0, solution of x in terms of a

Help me to calculations the trial error some mathematics formula which i use everyday :)

Ram Wadbudhe

It confuses about the problem we type in . Please try to get a keyboard like mathway.

Trash, it said everything was invalid

Presedent Papa Trumpu

Constantly told me equation is invalid even though the equation was perfectly valid

I love it but some themes would be nice tell me if you can thank you ❤

Great app Thnx alot, I could solve equations with multiple variables. This feature is what I hv bn looking for to match with the Solve Function of my old Casio fx570mx. But it doesn't seem to hv a means to save the equations/formulas entered.

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.

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 .

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.

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.

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.

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

Its really useful but... Its really easy tu use and it give you a quick answer but it doesnt give you the processes of the equations only the results that why i dont love it because my teacher sais that if i dont right the whole processes it counts like i didnt do the homework quick tip: if you dont know how the app works use the tutorial just swipe from left to right and press the tutorial button

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

I think im in love Amazinggg... im a busy teen who doesnt have time for homework that these teachers are giving so this was a great time saver

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

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

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

Alex Gwyn April 28, 2015

Hey opal, you can use the division symbol " / " to do division and enter fractions. Fractions would be in the form of "(1/2)" or something similar!
Thanks 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

Alex Gwyn March 12, 2015

Hey Fuska, to do exponents you can use the "^" operator. So 3^2 would be "3 squared", you can also use the "sqrt(" button to do square roots. If you have any more questions check out the tutorial in the app or email me at alagoapps@gmail.com Good app Some problems with Logarithmic equations, but its not incorect

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

...! 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

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.

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

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

Alex Gwyn November 20, 2014

Hey Maria! I can assure you I have done a lot of testing to make sure the answers are right! As long as the answers are in the range they will be found! If you have any concerns please email me at alagoapps@gmail.com 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. :)

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

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

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

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

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

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

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

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

Alex Gwyn January 3, 2015

Hey Shivang, I'm sorry the app doesn't seem to be working for you. Could you email me some example of the equations you are having trouble with at alagoapps@gmail.com. Thanks! Review deleted
