When you want to share your hand work with bob for help on troubleshooting errors, please do not imbed cell phone photos of it in the body of an email, because they are often sideways or too small to easily read, then I have to try to extract them and manipulate them before helping you. [Okay, I will still try to work with cell phone photos.]
Work on 8.5x11 inch white paper and use the free app Adobe Scan to scan your page or pages to a single PDF document, which you can then "share" with yourself by email to yourself, and then you can forward it to me with your questions about what went wrong, or extract it first to a PDF on your computer.
Adobe Scan (review, download) automatically frames an 8.5x11 inch sheet (placed on a darker background) and automatically snaps a photo scan of that sheet, correcting the image for viewing angle to become rectangular, and eliminating poor lighting and shadow effects automatically, and easily allowing multiple sheet pages in the same file. It also allows for manual intervention to select the edges of the document if necessary or to redo a page scan. This is very user friendly and produces optimum results. [Other apps are acceptable ONLY IF they deliver the same clean quality scans as Adobe Scan.] To avoid reminders to convert to editable text, you can fix your settings to not do OCR (optical character recognition). You just set up a free account like many apps and you are in business.
Hand work should be done with a black pen for better scanning, or at least a dark pencil and not too tiny sized writing. Light pencil work and small print is difficult for bob to read. It is much better to use pen and if you decide to change your work, simply cross it out clearly, and continue. Sometimes students erase correct work, leaving no record behind. Erasing is dangerous because it removes some of your thinking process from the calculation.
