Sorry guys, what sensor can I use to detect numbers written on a white piece of paper and send the number to the Arduino board??

Hey, this is an image processing task therefore it requires a camera and an algorithm to decipher the data. You can find references online, for example - https://www.pyimagesearch.com/2017/02/13/recognizing-digits-with-opencv-and-python/.
Good luck!
