6 7 7 3 1=?
7 4 3 2 6=?
8 3 6 4 2=?

6 + 7 - 7 - 3 - 1 = 2
7 + 4 + 3 - 2 * 6 = 2
8 - 3 - 6 / 4 * 2 = 2

6 + 7 - 7 - 3 * 1 = 3
7 - 4 + 3 * 2 - 6 = 3
8 + 3 - 6 - 4 + 2 = 3

6 + 7 - 7 - 3 + 1 = 4
7 + 4 - 3 + 2 - 6 = 4
8 - 3 / 6 * 4 - 2 = 4

6 - 7 / 7 + 3 - 1 = 7
7 + 4 * 3 - 2 * 6 = 7
8 + 3 - 6 + 4 - 2 = 7

6 + 7 - 7 + 3 - 1 = 8
7 + 4 * 3 / 2 * 6 = 8
8 + 3 - 6 / 4 * 2 = 8

6 + 7 - 7 + 3 * 1 = 9
7 * 4 / 3 - 2 / 6 = 9
8 + 3 + 6 - 4 * 2 = 9

6 + 7 - 7 + 3 + 1 = 10
7 + 4 + 3 + 2 - 6 = 10
8 * 3 - 6 - 4 * 2 = 10

6 + 7 / 7 + 3 + 1 = 11
7 + 4 + 3 * 2 - 6 = 11
8 + 3 + 6 - 4 - 2 = 11

6 + 7 + 7 - 3 - 1 = 16
7 + 4 - 3 + 2 + 6 = 16
8 * 3 - 6 - 4 + 2 = 16

6 + 7 + 7 - 3 * 1 = 17
7 * 4 - 3 - 2 - 6 = 17
8 + 3 * 6 / 4 * 2 = 17

6 + 7 + 7 - 3 + 1 = 18
7 + 4 + 3 - 2 + 6 = 18
8 + 3 * 6 - 4 * 2 = 18

6 - 7 + 7 * 3 - 1 = 19
7 + 4 * 3 / 2 + 6 = 19
8 + 3 + 6 + 4 - 2 = 19

6 - 7 + 7 * 3 * 1 = 20
7 + 4 + 3 / 2 * 6 = 20
8 + 3 * 6 - 4 - 2 = 20

6 - 7 + 7 * 3 + 1 = 21
7 * 4 - 3 + 2 - 6 = 21
8 * 3 - 6 / 4 * 2 = 21

6 + 7 + 7 + 3 - 1 = 22
7 + 4 + 3 + 2 + 6 = 22
8 * 3 + 6 - 4 * 2 = 22

6 + 7 + 7 + 3 * 1 = 23
7 + 4 + 3 * 2 + 6 = 23
8 + 3 + 6 + 4 + 2 = 23

6 * 7 - 7 - 3 - 1 = 31

大概算了一下都能等于23。
6+7+7+3÷1=23
7+4+3×2+6=23
8+3+6+4+2=23


答案是23
6+7+7+3*1=23
7+4+3*2+6=23
8+3+6+4+2=23

6+7+7+3X1=23

7X4+3-2-6=23

8+3+6+4+2=23
