✔ 最佳答案
(-2) + (+2) - (-1) x (1-7)除 6-2= -2 + 2 + - ( -1 ) x ( - 6 ) 除 6 - 2
= - 6除6 - 2
= - 1 - 2
= -3
應該岩，用多功能計數機計過!!!

(-2) + (+2) - (-1) x (1-7) 除 6-2
=(-2)+(+2)-(-1)x(-6)÷(+4)
=(-2)+(+2)-(+6)÷(+4)
=(-2)+(+2)-(+1.5)
=(-2)+2-1.5
= -1.5
=(-2)+(+2)-(-1)x(-6)÷(+4)
=(-2)+(+2)-(+6)÷(+4)
=(-2)+(+2)-(+1.5)
=(-2)+2-1.5
= -1.5

(-2) + (+2) - (-1) x (1-7) 除 6-2 =
Step 1: (-2)+(2)-(-1)x(-6)/6 - 2
Step 2: (-2)+(2)-(-1)x(-1) - 2
Step 3: (-2)+(2)-(1) - 2
Step 4: -(1) - 2
Ans: -3
Step 1: (-2)+(2)-(-1)x(-6)/6 - 2
Step 2: (-2)+(2)-(-1)x(-1) - 2
Step 3: (-2)+(2)-(1) - 2
Step 4: -(1) - 2
Ans: -3

(-2) + (+2) - (-1) x (1-7) / 6-2
=-2+2+1 X (-6)/4
=-2+2 + (-1.5)
=0 + (-1.5)
=-1.5
=-2+2+1 X (-6)/4
=-2+2 + (-1.5)
=0 + (-1.5)
=-1.5

(-2) + (+2) - (-1) x (1-7) / 6-2
= -2 + 2 + - ( -1 ) x ( - 6 ) / 6 - 2
= - 6 / 6 - 2
= - 1 - 2
= -3
