Thomas Rushton explains the order of operations, particularly around boolean operators:

The order in which calculations are done – not just reading from left to right, but remembering that things like multiplication and division happen before addition and subtraction. My son tells me that kids nowadays are being taught something called “BIDMAS” – which stands for “Brackets, Indices, Division, Multiplication, Addition, Subtraction”. Or it can be BODMAS – Brackets, Operations, Division… (Operation is a fancy new way of describing indices – ie x

^{y})Unsurprisingly, there are similar rules for Boolean operators.

It’s a valuable lesson oft learned.
