How to scan a problem?
To solve a math problem, point the camera at your math problem to take a picture and Photomath will show you the solution or solutions.
Holding firmly and writing with a neat handwriting will make scanning faster.
If the result is not shown after two to three seconds, then either the math problem is not supported or the app is unable to properly recognize the text (for example, due to poor light conditions or camera not being clean).
You can use the math keyboard to input the problem manually.
How to resize the viewfinder?
Tap and hold with one finger in the bottom right corner of the rectangle and drag in any direction to resize the screening window, until you get the optimal scanning size.
How to edit a scanned problem?
If you want to modify a scanned problem, tap the edit icon (looks like a pen) next to the appeared solution and edit it in the calculator.
