  • 先化简,再计算

    1+(-9)= 8+(+20)= 78-8+(-92)÷77= 87-9+9=

    1+1-9+8=

    去括号

    -(1-9+8-6-3)= -[-(88-99+66+59-77-100)]=

    82-99-5+6-(-6)= 1087-(8)-9+72-(95+885)=

    计算

    2 3 3 1

    (-8)-4 = 72-56+(-5) = 52-(——)×104+99=

    52

    1 2 100

    53 -(-6)= 54+(-0) =

    1 1

    99÷5+99-63×——= 88÷(——)×3×4-22+6=

    2 4

    2 3

    8×(-7)÷4÷7-6+8= 7×7-(-1)÷4+8=

    1 1 1

    [73+(56)]÷3= ( 82)+(43)÷2×5=

    (88-73)×62-(-80)= 100-(-8)+8-(8)= 100÷(-100)×9=

    44÷4×3-4-4+(-55)= 77÷11-(-3)×5=

    81÷3×2-1+258= 51×2+8-(-1)+89= 共26个
