      Press [XEQ] then followed by
      [ALPHA] [Gold Shift] [ % ] [ C ] [ H ] [ALPHA]
      For example to find the percentage difference between the value of 100 and 125.
      Type 100
      Press [Enter]
      Type 125
      Press [XEQ] then followed by
      [ALPHA] [Gold Shift] [ % ] [ C ] [ H ] [ALPHA]
      It should display the answer of
      25
