boolean algebra - Is writing equalities within an equation abuse of notation?



I'll occasionally write equalities within parentheses or sqrt signs to make my steps more compact.



E.g.:




r=34479167=169=3443=34=32



I always assumed this was pretty clear, and an acceptable (if unusual) way to use equalities.
However, I was recently told that "you can't take the root of a truth value", which is certainly true.



Is my notation confusing? Does it classify as abuse of notation?



Is the below correct?



r=(79167=169)r=


Answer



Your notation is very non-standard and will be confusing to most people. Many people use curly braces to denote intermediate results:
r=344791674169=3443=34=32
