WebJun 19, 2023 · For example –. Infix notation: (A-B)*[C/(D+E)+F] Post-fix notation: AB- CDE +/F +*. Here, we first perform the arithmetic inside the parentheses (A-B) and (D+E). The division of C/ (D+E) must be done prior to the addition with F. After that multiply the two terms inside the parentheses and bracket.
