Đáp án:
1)(-37) + 14 + 26 + 37
= [(-37)+37]+(14+26)
=0+40=40
2)-24+6+10+25
=(-24+24)+(6+10)
=0+16=16
3) 15+23+(-25)+(-23)
=[15+(-25)+[23+(-23)]
=-10+0=-10
4)60+33+(-50)+(-33)
=[60+(-50)]+[33+(-33)]
=10+0=10
5) (-16)+(-209)+(-14)+209
=[(-16)+(-14)]+[(-209)+209]
=-20+0=-20
6) (-12)+(-13)+36+(-11)
=(-25)+(-11)+36
=-36+36=0
7) -16 + 24 + 16 – 34
= -10
9) 25+37-48-25-37
=(25-25)+(37-37)-48
=0+0-48
=-48
10) 2575 + 37 - 2576 -29
= 2575 - 2575 + 37 - 29
= 0 + 37 - 29
= 8
11) 34+35+36+37-14-15-16-17
=(34-14)+(35-15)+(36-16)+(37-17)
=20+20+20+20
=80
