Final answer:
The operator evaluated last in an expression depends on the order of operations in programming. In this case, the plus (+) operator is evaluated last because it is an arithmetic operator.
Step-by-step explanation:
The operator evaluated last in an expression depends on the order of operations in programming. In general, arithmetic operators, such as +, -, *, /, are evaluated before comparison operators like ==. So, in this case, the operator **+** is evaluated **last** because it is an arithmetic operator.
