Pascal was quite confusing for me. I could never remember to add
parentheses to expressions like "x >= 0 and x <= 10". To give 'and'
and '*' the same priority is an example of a logical, simple, and bad
decision.

C has more priorities than Lua because it has (much) more operators. If
you consider only the common subset, operators in Lua and C have
basically the same priorities. (I think the only difference is that
in C '==' has lower precedence than '<'; in Lua they have the same
precedence.)

A (the?) great source of confusion in C priorities is '&' and '|',
which for historical reasons have a "wrong" priority.
