Yes, in this case parentheses are a must.
I also llike putting them when the reader may not guess the precedence
correctly easily. This reader can be myself later ;-).

I have a colleague who for reasons only known to himself is violently against "unnecessary" parentheses, so I always put in even more just for him.

My rule is to parenthesise wherever multiple operators appear in an _expression_.  Even more important where the team is working in multiple programming languages with different precedence rules.
