递等式计算(1)4357+6503-2 498(2)376×18÷47(3)6495-2 618÷1

1个回答

  • 解题思路:(1)(2)(4)都是从左往右依次计算;

    (3)先算除法,再算减法;

    (5)先算括号里面的除法,再从左往右依次计算;

    (6)小算先算括号里面的,再算乘法和减法.

    (1)4357+6503-2498,

    =10860-2498,

    =8362;

    (2)376×18÷47,

    =6768÷47,

    =144;

    (3)6495-2618÷14,

    =6495-187,

    =6308;

    (4)12096÷27÷16,

    =448÷16,

    =28;

    (5)600÷(100÷25)×4,

    =600÷4×4

    =600;

    (6)812-34×(50-32),

    =821-34×18,

    =821-612,

    =200.
