Answer 1

a273100179 ，你好：
((3*13)+-7)-8
(3*13)+(-7-8)
(3*13)-(8--7)
((3*13)-8)+-7
(-7-(3-13))*8
((-7-3)+13)*8
-7+((3*13)-8)
(-7+(3*13))-8
-7-(8-(3*13))
(-7-8)+(3*13)
-7-(8-(13*3))
(-7-8)+(13*3)
((-7+13)-3)*8
(-7+(13-3))*8
-7+((13*3)-8)
(-7+(13*3))-8
8*(-7-(3-13))
8*((-7-3)+13)
8*((-7+13)-3)
8*(-7+(13-3))
8*(13-(3--7))
8*((13-3)+-7)
8*((13+-7)-3)
8*(13+(-7-3))
(13-(3--7))*8
((13-3)+-7)*8
((13*3)+-7)-8
(13*3)+(-7-8)
(13*3)-(8--7)
((13*3)-8)+-7
((13+-7)-3)*8
(13+(-7-3))*8

Answer 2

3 × 13 -7 -8=24
8 × (13 - 7 - 3)=24
