( - 8 ) - ( + 12 ) ( - 11 ) - ( + 7 ) ( -6 )
= -8- ( -132 ) - ( - 42)
= - 8+ 132+ 42
=166
= -8- ( -132 ) - ( - 42)
= - 8+ 132+ 42
=166

( - 8 ) - ( + 1 2 ) ( - 1 1 ) - ( + 7 ) ( - 6 )
= - 8 - ( - 1 3 2 ) - ( - 4 2 )
= - 8 + 1 3 2 + 4 2
= 1 6 6
= - 8 - ( - 1 3 2 ) - ( - 4 2 )
= - 8 + 1 3 2 + 4 2
= 1 6 6

166
-8-(-12*11)-(-7*6)
-8+132+42
-8+174
166
-8-(-12*11)-(-7*6)
-8+132+42
-8+174
166

(-8) - (+12)(-11) - (+7)(-6)
= (-8) - (- 12 x 11) - (- 7 x 6)
= (-8) - (- 132) - (- 42)
= -8 + 132 + 42
= -8 + 174
= 174 - 8
= 166

各位,為何12 x 11 = 121??12 x 11 應是132呀!話明個明係2, 個答案點會係1架??就算1 x 2 都唔會等於1, 應是2
= (-8) - (- 12 x 11) - (- 7 x 6)
= (-8) - (- 132) - (- 42)
= -8 + 132 + 42
= -8 + 174
= 174 - 8
= 166
