It might not work for you, but for me it helps alot. I use this as a last resort to a problem i just can't solve so i pull this out and get it right, sometimes the answer is not simplified, or the correct answer can be difficult to find, but even with the calculator alone not including the photo aspect, makes understanding math so much easier! 10/10 by far.
This app is so amazing. I would recomend altough it dosent always show the work unless you watch an ad, helps with homework, explains how to get the answer, and has multiple ways to answer a question or figure out a problem, tried a few sample problems and already i can tell this app is awesome.
