\(5642+1642+4358-642\)
\(=\left(5642+4358\right)+\left(1642-642\right)\)
\(=10000+1000\)
\(=11000\)
5642 + 1642 + 4358 - 642
= (5642 + 4358) + (1642 - 642)
= 10000 + 1000
= 11000
5642 + 1642 + 4358 - 642
= (5642 + 4358) + (1642 - 642)
= 10000 + 1000
= 11000
5642 + 1642 + 4358 − 642
= ( 5642 + 4358 ) + ( 1642 − 642 )
= 10 000 + 1000
= 11 000
