Answer 2

\(237+2456+1763+544\)

\(=\left(237+1763\right)+\left(2456+544\right)\)

\(=2000+3000\)

\(=5000\)

Answer 3

    237 + 2456 + 1763 + 544

= 237 + 1763 + 2456 + 544

= (237 + 1763) + (2456 + 544)

= 2000 + 3000

= 5000

Answer 4

237 + 2456 + 1763 + 544

= ( 237 + 1763 ) + ( 2456 + 544 )

= 2000 + 3000
