=1000.10.2002=10000.2002=20020000 =28.(47+43)+72.(29+61) =26.27.2+52.73
B)36.42+2.17.18+9.41.6=36.42+(2.18).17+9.41.6 =28.90+72.90 =(26.2).27+52.73
= 36.42 +2.17.18+41 .54 =90.(28+72) =52.27+52.73
=(36+54).(42+18).(41+2+17)=90.60.60=324000 =90.100=9000 =52.(27+73)=52.100=5200

\(S=2-4+6-8+...+2004-2006\)
\(S=\left(2-4\right)+\left(6-8\right)+...+\left(2004-2006\right)\)
\(S=\left(-2\right)+\left(-2\right)+...+\left(-2\right)\)
\(S=1004\times\left(-2\right)\)
\(S=-2008\)
8*9=72
23.32=8.9=72
Xong rồi đó
