Answer 1

 Bài 2:

a) 132 + 237 + 868 + 763

= ( 132 + 868 ) + ( 237 + 763 )

= 1000 + 1000

= 2000

c) 25 . 198 . 4

= 198 . ( 25 . 4 )

= 198 . 100

= 19800

Answer 2

e) 17 . 88 + 17 . 12

= 1496 + 204

= 1700

d) 5 . 25 . 2 . 37

= ( 5 . 2 ) . ( 25 . 37 )

= 10 . 925

= 9250

f) 12 . 35 + 35 . 182 - 35 . 94

= 420 + 6370 - 3290

= 10080

Answer 3

a.132+237+868+763=(132+868)+(237+763)=1000+1000=2000.  

b.(35-17)+(17+20-35)=(35-35)+(17-17+20)=20.                            

c.25x198x4=(25x4)x198=100x198=19800                                    

d.5x25x2x37=(5x2)x(25x37)=10x925=9250.                                      

e.17x88+17x22=17x(88+22)=17x1110=18870                            

f.12x35+35x182-35x94=35x(12+182-94)=35x100=3500
