Operators with the highest precedence appear at the top of the list. Within an expression, operators Operators with the highest precedence appear at the top of the list. Within an expression, operators
with higher precedence will be evaluated first. with higher precedence will be evaluated first. When two or more operators of the same precedence is
present in an expression, then the associativity of the operator tells us the order in which the operators
must be evaluated. The associativity in the given list is from left to right i.e, operators in the left are
evaluated first.
