In postfix notation, operators are placed after their respective operands. 
Applying postfix notation to the expression, we have:
a b - c d + *
First, we subtract b from a, then add c and d before performing the multiplication. Therefore, the postfix expression (a b - c d + *) is equivalent to the expression (a - b) * (c + d).

The Following Expression (A - B) * (C + D)
