✔ 最佳答案
1. 500-650÷13×6＝500-50×6
＝500-300
＝200
2. (182+5 ×12)÷12
＝(182+60)÷12
＝242÷12
＝20.17

1. 500-650/13x6
=500-50x6
= 500-300
=200
2. (182+5x12) /12
= (182+60)/12
= 242/12
=20...2
=500-50x6
= 500-300
=200
2. (182+5x12) /12
= (182+60)/12
= 242/12
=20...2

記住先乘除後加減，括號行先的口訣。
(1) 500 - 650 / 13 x 6 = 500 - 300 = 200
(2) (182 + 5 x 12) / 12 = (182 + 60) / 12 = 242 / 12 = 20 1/6 (20又6份1)
(1) 500 - 650 / 13 x 6 = 500 - 300 = 200
(2) (182 + 5 x 12) / 12 = (182 + 60) / 12 = 242 / 12 = 20 1/6 (20又6份1)

1 500-650除13乘6
500 - 650 ÷ 13 x 6
=500 - 50 x 6
=500 - 300
=200
2 (182+5乘12)除12
是192嗎?
(192 + 5 x 12) ÷ 12
=192÷12 + 5
=16 + 5
=21
500 - 650 ÷ 13 x 6
=500 - 50 x 6
=500 - 300
=200
2 (182+5乘12)除12
是192嗎?
(192 + 5 x 12) ÷ 12
=192÷12 + 5
=16 + 5
=21
