\(\frac{2999997}{6}\)-\(\frac{1999998}{6}\)-\(\frac{999999}{6}\)=0

bằng 0

999999/2-999999/3-999999/6=0

1988998 nhé bn

999999+999999-[6000+5000]=1988998

k nha!

:3))

\(999999+999999-11000\)

=\(1999998-11000\)

=\(1988998\)

Chuc bn hok good

(9+99+999+9999+...........+999.....99999)+100

=(10+100+1000+......+100000.......000)-100

=1111111......1110(99 chu so 1)- 100

   9 + 99 + 999 + .....................+ 99999..999 ( 100 chữ số chữ số 9 )

= 9 + 9 * 11 + 9 * 111+........+ 9 * 111..11 ( 100 chữ số chữ số 1)

= 9 *  ( 1 + 11 + 111 + ... + 1111..1)( 100 chữ số chữ số 1)

= 9 *               A

= .... ( các bạn tự tính kết quả nhé )

cách tính của hoang quan chậm hơn mà khó hiểu hơn nữa

999 999 + 999 999 = 1999998

Ta có: \(B=\frac{999999}{2}-\frac{999999}{3}-\frac{999999}{6}\)

\(B=999999\times\frac{1}{2}-999999\times\frac{1}{3}-999999\times\frac{1}{6}\)

\(B=999999\times\left(\frac{1}{2}-\frac{1}{3}-\frac{1}{6}\right)\)

\(B=999999\times\frac{3-2-1}{6}\)

\(B=999999\times\frac{0}{6}\)

\(B=999999\times0\)

\(B=0\)

Vậy \(B=0\) .

999999+1=1000000

1000000

=1000000

999999x90000=89999910000
