Convert the following infix expressions into postfix form

1. a / b / c - (d+e) * f

2. a - (b+c)

3. a - (b + c * d) / e

Solution

1. a / b / c - (d+e) * f

   = a/b/c-(de+)*f
   =(ab/)/c-(de+)*f
   =(ab/c/)-(de+)*f
   =(ab/c/)-(de+f*)
   =ab/c/de+f*-

2. a - (b+c)
   = a-(bc-)
   = abc--

3. a - (b + c * d) / e
   = a-(b+(cd*))/e
   = a-(bcd*+)/e
   =a-(bcd*+e/)
   =abcd*+e/-
