không trừ được

 45 - 37 x 12 = -399

nhân chia trước, cộng trừ sau-_-

a, 22,56 - 7,59 - 8,41 = 22,56 - ( 7,59 + 8,41 ) = 22,56 - 16 = 6,56

b, 53,48 - 19,84 - 22,16 = 53,48 - ( 19,84 + 22,16 ) = 53,48 - 42 = 11,48

c, 14,23 + 7,06 - 1,23 = ( 14,23 - 1,23 ) + 7,06 = 20,06

d, 20,06 - 12,37 - 7,63 = 20.06 - ( 12,37 + 7,63 ) = 0,06
