19999+9999×9999
=10000+9999+9999×9999
=10000+9999×(9999+1)
=10000+9999×10000
=10000×(9999+1)
=10000×10000
=100000000
19999+9999×9999
=10000×10000
=100000000
19999+9999×9999
=10000+9999+9999×9999
=10000+9999×(1+9999)
=10000+9999×10000
=10000×(1+9999)
=10000×10000
=100000000
10000+9999(1+9999)=10000+9999x10000=10000(1+9999)=100000000
=10000+9999+9999X9999
=10000+9999X(9999+1)
=10000+9999X10000
=10000X(9999+1)
=100000000
19999+9999×9999
=10000+9999+9999x9999
=10000+9999x(9999+1)
=10000+99990000
=100000000
19999+9999×9999=
10000+9999+9999×9999=
10000+9999×(9999+1)=
10000+9999×10000=
10000×(9999+1)=
100000000
19999+9999×9999
=10000+9999+9999×9999
=10000+9999×(1+9999)
=10000+9999×10000
=10000×(1+9999)
=10000×10000
=100000000
可以这样做
