Answer 1

How many what"Method kids can try:

① 999²=999×999

=1000×999–1×999

=(999×1,000)–999

=(1,000×1,000–1×1,000)-1000+1

=1,000,000–1,000-1,000+1

=1,000 thousands-2 thousand+1

=998 thousands+1

=998,000+1

=998,001

② 999²

=999*999

=998*999+999

=999*998+(998+1)

=999×998+1×998+1

=One thousand of 998 +1

=998,000+1

=998,001

③ 999²

=999*999

=999*999+999-999

=999*999+1*999–1,000+1

=one thousand of 999–1,000+1

=999 thousands - 1 thousand +1

=998 thousands +1

=998,001

④999*999-1=999*999+999-999-1

999*999–1=1,000*999–1,000

999²-1=999*1,000–1,000

999²-1=998,000

999²=998,000+1=998,001
