Answer 1

((2+2)*(10-4))
((2*2)*(10-4))
((2+2)*(10-4))
((10-(2+2))*4)
((10-(2*2))*4)
((10-(2+2))*4)
((2+10)/(2/4))
((2+10)/(2/4))
((4-2)*(2+10))
((4-2)*(2+10))
((10-(2-4))*2)
(((4-2)+10)*2)
(((4-2)+10)*2)
((10+2)/(2/4))
((10+2)/(2/4))
((4-2)*(10+2))
((4-2)*(10+2))
(((2+10)/2)*4)
(4/(2/(2+10)))
(((2+10)/2)*4)
(4/(2/(2+10)))
(((10-2)-2)*4)
((2+10)*(4-2))
((2+10)*(4/2))
((2+10)*(4-2))
((2+10)*(4/2))
(((2+10)*4)/2)
((4-(2-10))*2)
(((2+10)*4)/2)
(((10-2)+4)*2)
(((10-2)+4)*2)
((4/2)*(2+10))
((4/2)*(2+10))
(((4/2)+10)*2)
(((4/2)+10)*2)
((4/2)*(10+2))
((4/2)*(10+2))
(((4+10)-2)*2)
(((4+10)-2)*2)
(((10-4)*2)*2)
((10-4)*(2+2))
((10-4)*(2*2))
((10-4)*(2+2))
(((10+2)/2)*4)
(4/(2/(10+2)))
(((10+2)/2)*4)
(4/(2/(10+2)))
((10+2)*(4-2))
((10+2)*(4/2))
((10+2)*(4-2))
((10+2)*(4/2))
(((10+2)*4)/2)
(((10+2)*4)/2)
(((10+4)-2)*2)
(((10+4)-2)*2)

Answer 2

(2+2)×(10-4)=24；（10-4）×2×2=24
