Answer Posted / poonam khandar
Parenthesis are used to define the sequence or priority of
execution of operations in given infix expression. When we
write an espression in prefix or postfix format we have
already considered the order of execution and only evaluate
the expression starting from left towars right in the
sequence the operators and operands are encountered.
