1) In the postfix notation, the operator comes after the operands.

2) The postfix expression for the infix expression "3 + 4 * 2" is "3 4 2 * +".

3) Postfix notation is also known as reverse Polish notation.

4) The computer program converts infix expressions to postfix expressions for evaluation.

5) Postfix is commonly used in computer science for parsing mathematical expressions.

6) Postfix notation can be used to avoid the need for parentheses in mathematical expressions.

7) The postfix evaluation algorithm scans the expression from left to right.

8) After converting the infix expression to postfix, the computer can easily evaluate it.

9) Postfix expressions are often used in calculators for simplicity and efficiency.

10) Understanding postfix notation is important for implementing certain algorithms in computer science.

11) I'm sorry, but 'Postfix' is not a common word in everyday language.
