I like it very much                 Very nice

Ive been searching for a game like this I am so intrigued by this type of game Estoy muy feliz que finalmente lo encontre The interface is a bit boring pero no me importa I must add that I LOVE the icon                 Cinco Estrellas

Fantastic and a productive use of idle time I find this app very challenging and hard to put down I visited the developers website and found an identical Mac application downloadable for free as well Thank you so very much The only issue I have is I wish that there was an option or default that would not immediately clear out a puzzle equation after a few seconds of viewing The viewer should be able to tell the app when to clear a solved puzzle in Free mode Some of us need additional time to review even if we solved the problem Sometimes your frustrated and forced to guess Sometime you prefer to try and tackle the next problem and hopefully come back to the problem that you couldnt solve later It would be great to see this app expanded with features such as these Even still its a very powerful app for those of us who like loosing our hair over math problems Please expand the apps feature set if you can Thanks for making this a free app Ive been searching the app store for a number of like minded applications that provide problems and ask the user to solve them in a like manner I think this app should be the template for others No fluff animations or other things you dont need Just problems to solve I hope that you further this idea and introduce a series of similar apps Thank you                 Fun challenging and more
