3 2
[-3乘2除+(-2)乘3-4乘(-6)]除(-3 )
[(-3)x2/+(-2)x(3-4)x(-6)]/(-3)
=[-6/2x(-6)]/(-3)
=[(-3)x(-6)]/(-3)
=18/(-3)
=-6

x=乘

[-3乘2除+(-2)乘3-4乘(-6)]除(-3 )
= [ -3*2/(-2)*3-4*(-6) ] / (-3)
= [ -3*2*3/(-2) + 4*6 ] / (-3)
= [9 + 24] / (-3)
= 33 / (-3)
= -11

算式係 [-3×2÷(-2)×3-4×-6]÷-3 ?

[-3×2÷(-2)×3-4×-6]÷-3
= [-3×2÷-2×3-4×-6]÷-3
= [-6÷-2×3-(-24)]÷-3 <<先乘除後加減..
= (3×3+24)÷-3
= (9+24)÷-3
= 33÷-3
= -11

沒有參考答案嗎.....
