\(\frac{2999997}{6}\)-\(\frac{1999998}{6}\)-\(\frac{999999}{6}\)=0
(9+99+999+9999+...........+999.....99999)+100
=(10+100+1000+......+100000.......000)-100
=1111111......1110(99 chu so 1)- 100

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 \(B=0\) .
