✔ 最佳答案
(一8)x(一5)=40
因為負數x負數, 答案一定係正整數, 所以見到這樣的數, 只要直接想8x5等於幾多就行了
可以試下記住: 負負得正(一8)x(一5)=40
正正得正 8x5=40
正負得負 (一8)x5=(一40)
參考: 自己

(一8)x(一5)
=40
因為負負得正,正正得正,正負得負
例如:
(一8)x(5)
=一40
8x5
=40
=40
因為負負得正,正正得正,正負得負
例如:
(一8)x(5)
=一40
8x5
=40

(-8)X(-5)
=8x5
=40
because 負負得正,,so (-8)x(-5)==8x5
=8x5
=40
because 負負得正,,so (-8)x(-5)==8x5

(-8)x(-5)
=8x5
=40
=8x5
=40
