Absolute value inequality calculator online

It helps with so much trust me, the app is very helpful when my mind has gone blank and I don't want to do any math. Granted, there are a few bugs, particularly with the camera, and a few with the caluclation process (to be exact it sometimes says it can't calculate a question but it can).

Everything is great, except that when i do tge photo thing, its not working so i have to write the whole exercise in the calculator space. This is my first time writing a review for an app. Best app ever to use for math problems.
