    1) 67+135+33=(67+33)+135=100+135=235
    2) 277+113+323+87=(277+323)+(113+87)=600+200=800
    3) 86+357+14=(86+14)+357=100+357=457
    4) 72+69+128=(72+128)+69=200+69=269
    5) 25.5.4.27.2=(25.4).(27.5.2)=100.270=27000
    6) 25+64+26+385=(25+385)+(64+26)=410+90=500
    7) 125.2.41.8=(125.8).(41.2)=1000.82=82000
    8) 8.12.125.2=(125.8).(12.2)=1000.24=24000
    9) 4.36.25.50=(4.25).(36.50)=100.1800=180000
