✔ 最佳答案
圖片參考：http://tw.yimg.com/i/tw/ugc/rte/smiley_35.gif
(-8)(-1/3)(+1/4)(-6)
= (-8)(-3/1)(1/4)(-1/6)
= (-8)(-3)(1/4)(-1/6)
= 24 (1/4)(-1/6)
= 6(-1/6)
= -1

唔好意思,附號亂左!
用x代剩號,Y代除號
(-8)Y(-1/3)x(+1/4)Y(-6)
= (-8)x(-3/1)x(1/4)x(-1/6)
= (-8)x(-3)x(1/4)x(-1/6)
= 24 x(1/4)x(-1/6)
= 6 x(-1/6)
= -1

(-8)÷(-1/3)×(+1/4)÷(-6)=?
(-8)÷(-1/3)×(+1/4)÷(-6)
= -( 8×3×1/4×1/6 )
= -( 24× 1/24 )
= -1
(-8)÷(-1/3)×(+1/4)÷(-6)
= -( 8×3×1/4×1/6 )
= -( 24× 1/24 )
= -1
