A quick explanation of why "and/or" shouldn't be used in written English.
Note: The OR allows for the same True result as the AND (bottom right corner), while also allowing for other combinations producing True results.
Sometimes people mean "and/exclusive or" when they type "and/or" however this would look extremely strange when written and 99% of the time a simple or will suffice.
Therefore all written usage of "and/or" should simply be "or".
