答案：
(1)1234+700+300 (2)350+195+105+850
(3)132+(68+54)
=1234+(700+300) =(350+850)+(105+195)
=132+68+54
=1234+1000
=1200+300 =200+54
=2234 =1500 =254
(4)26+(89+74) (5)23
=26+74+89 =23
=100+89
=23
=189 =230
=336
(7)356-147-100-53 (8)287+36+13
(9)432-123-77
=356-(147+100+53)
=287+13+36 =432-(123+77)
=356-300 =300+36
=432-200
=56 =336
=232
(10)435-(135+189)
(11)317-49-11-40 (12)369-142-58
=435-135-189
=317-(49+11+40) =369-(142+58)
