The “XOR” versus “Sum modulo 2”

Logic elements, which are the basis of modern digital technology, are based on the use of Boolean logic. In 1854, George Boole proposed for the first time to investigate logical statements by ...

Excel Boolean logic: How to sift spreadsheet data using AND, OR, NOT, and XOR

In Excel, Boolean logic (a fancy name for a simple condition that’s either true or false) is one way to sift specific data or results from a large spreadsheet. Granted, there are other ways to search ...
