The order of precedence is less well defined for logic circuits, like XOR or NAND, which are derived from the three basic circuits. It is best to use parenthesis to clarify the order of operations ...

Even if you don’t have this kit in your hands, you should be able to take images I included in this article, map the traces, and crack the code to figure out the circuit. I’m smitten. AND!XOR ...

which are critical factors in modern circuit design. Additionally, researchers have focused on designing specific logic gates, such as XOR/XNOR cells, that are resilient to voltage and temperature ...
