(+4)*(-5) - (-6) / 3*(+3)-4*(-5)-1
=（-20） + 6 / 9 + 20 -1
= -14 /28
= -1/2
=負2分1

下次粉分綫用 [/] 來代替就可以了/ = 徐= 分綫
=（-20） + 6 / 9 + 20 -1
= -14 /28
= -1/2
=負2分1

(+4) * (-5) - (-6)
= (-20) - (-6)
= (-14)
(+3) * (+3) - (+4) * (-5) - (+1)
= (+9) - (-4) * (-5) - (+1)
= (+9) - (-20) - (+1)
= (+29) - (+1)
=(+28)
= (-20) - (-6)
= (-14)
(+3) * (+3) - (+4) * (-5) - (+1)
= (+9) - (-4) * (-5) - (+1)
= (+9) - (-20) - (+1)
= (+29) - (+1)
=(+28)
