  • 第一题:

    1:4 - (4 × (4 - 9))

    2:4 - 4 ×(4 - 9)

    3:4 + (4 × (9 - 4))

    4:4 + 4 ×(9 - 4)

    5:4 - (4 - 9) × 4

    6:4 - ((4 - 9) × 4)

    7:4 + (9 - 4) × 4

    8:4 + ((9 - 4) × 4)

    9:(4 × (9 - 4)) + 4

    10:4 × (9 - 4) + 4

    11:(9 - 4) × 4 + 4

    12:((9 - 4) × 4) + 4

    第二题:

    14-13+11+12

    第三题:

    13-(15-14)+12

    第四题:

    1:(3 + 3 ÷ 7) × 7

    2:(3 + (3 ÷ 7)) × 7

    3:(3 ÷ 7 + 3) × 7

    4:((3 ÷ 7) + 3) × 7

    5:7 × (3 + 3 ÷ 7)

    6:7 × (3 + (3 ÷ 7))

    7:7 × (3 ÷ 7 + 3)

    8:7 × ((3 ÷ 7) + 3)

    第五题:

    1:8 ÷ (3 - 8 ÷ 3)
