The following table provides a reference when you need to know the operator precedence used by Ruby. The table lists all operators from highest precedence to lowest.

Ruby operators (highest to lowest precedence)
Method Operator Description
Yes [ ] [ ]= Element reference, element set

Yes & Bitwise `AND'
Yes ^ | Bitwise exclusive `OR' and regular `OR'
Yes <= < > >= Comparison operators
Yes <=> == === != =~ !~ Equality and pattern match operators (!= and !~ may not be defined as methods)
&& Logical `AND'
|| Logical `AND'
.. ... Range (inclusive and exclusive)
? : Ternary if-then-else
= %= { /= -= += |= &= >>= <<= *= &&= ||= **= Assignment
