1. a) 83.16+17.16 = (83+17).16 = 100.16 = 1600

   b) 32: { 160:[300-(175+21.5)]} = ?

   c) ( 20.16+11.16-23.16):16 = 16 [ 16 ( 20+11-23 ) = 16(16.8)

   = 8

2. Giải thích các bước giải:

   83.16+17.16

   =(83+17).16

   =100.16

   1600

   32:{160:[300-(175+21.5)]}

   =32:{160:[300-(175+105)]}

   =32:{160:[300-280]}

   =32:{160:20}

   =32:8

   =4

   (20.16+11.16-23.16):16

   =(20+11).16-23.16):16

   =(33.16-23.16):16

   =(33-23).16):16

   =(10.16):16
