1000 nhé

100 . 10 = 1000

100 . 10 = 1000

1 + 100 . 10 

= 1 + 1000 

= 1001 

nha bn

\(1+100.10=1+1000=1001\)

1+100.10=1+1000=1001

10000

100 x 100 = 10000

100.100=10000

bạn tích mình rồi mình tích bạn ok ko

10000 nhéTiến Đạt

100.100=10000

= 10000 k mình mình nhanh nhất

100.100+900

=100.1000

=100000

ai tích tớ tích lại

100,100+900=100000,100

nha ban

chuc ban hoc gioi

10900

500/100*100/10=5*10=50

500/100.100/10=5.10=50   nhớ tk mình nha

500/100=5 

100/10=10 

=> 500/100.100/10=5.10=50 

100.300-100.200-100.100

=100.(300-200-100)

=100.0

=0

100x300-100x200-100x100

=100x(300-200-100)

=100x0

=0
