  • (1)6.15+4.9-9.85,

    =11.05-9.85,

    =1.2;

    (2)1500÷25÷4,

    =1500÷(25×4),

    =1500÷100,

    =15;

    (3)19.92-(14.37-5.43),

    =19.92-8.94,

    =10.98;

    (4)432-(361+153÷17),

    =432-(361+9),

    =432-370,

    =52;

    (5)142+35×6-315,

    =142+210-315,

    =352-315,

    =37;

    (6)27×13+72×13+13,

    =(27+72+1)×13,

    =100×13,

    =1300.
