The dark art that is boolean algebra ...

Thanks John, and lovely to hear from you. I hope all is well …

I omit to mention this in the workbook, I’ll need to review and revise, thanks.

I’ve found that a great deal of the confusion that surrounds this topic for my students tends to be due to a failure to correctly consider the order of precedence of operators when simplifying expressions. Therefore I try to explicitly reference the order of precedence as much as possible when modelling etc.
