Interesting. Sum and product are one of the few math things that feel way more intuitive to me than programming symbols. OTOH I get insta-lost with the “dx” Leibniz notation. Also imo & and | ! are a lot more intuitive than whatever math uses for conjunction/disjunction.

btw these large scary math symbols are just for-loops

! is only intuitive because you're used to it. Traditionally "/" means or, but it's overloaded with division so that's out. && and || are just painful, but... Math (and in fact logic) use a "v" and "upside down "v", I never remember which is which, and wholeheartedly agree.

I remember that ‘∧’ is ‘and’ by the fact that it looks like the letter ‘A’ with the cross-bar removed.

When I studied electronic engineering, we used those symbols, but also sometimes ‘.’ For ‘and’ and ‘+’ for ‘or’.

It seems like those are actually being used as multiplication and addition. And multiplication is the usual use of the period operator in algebra. If a "positive" signal is treated as true, and no signal is treated as "false", this works.
