#### Amazing

With out this app I would have NEVER passed algebra. Also this thing solves it for you as you go or simplifies it. And at the bottom of your screen you can click the icon with three lines for instructions and details about it. I highly recommend this calculator. Thank you mathlab graphing calculator.

#### Good except

Results will not display in scientific notation for some. So, must count each digit for answer such as 137498765443356.
Please fix it. Otherwise, an excellent app.

#### Great application and value for the price. (10/20/13)

I recommend this for individuals who are learning algebra/how graphing works, & math all around. It allows multiple memory functions, you can enter as many equations, and it has many functions. The developer produces good updates. I'm more than satisfied with this application, and among the several I have purchased previously, this one is by far, the best that is currently available (10/20/13). ~robjeff76

#### my opinion is that it's amazing, but low on capabilities. for in

my opinion is that it's amazing, but low on capabilities. for instance, putting in sec(pi/2), the result is 1.63312393531954E16, instead of undef in radian or even 1.000376 in degree. those uncertainties for this app gives both the app and the user problems. so i'm hoping that ether Mathlab or the creator of the app try and add other capabilities to it.

#### Great App

I think everything is great about it. The only suggestion I have is to make it so you can graph inequalities.
