    a) 237 + 357 + 763
    = ( 237 + 763 ) + 357
    = 1000 + 357
    = 1357
    b) 2345 + 4257 – 345
    = ( 2345 – 345 ) + 4257
    = 2000 + 4257
    = 6257
    c) 4276 + 2357 + 5724 + 7643
    = ( 4276 + 5724 ) + ( 2357 + 7643 )
    = 10000 + 10000
    = 20000
    d) 3145 + 2496 + 5347 + 7504 + 4653
    = ( 2496 + 7504 ) + ( 5347 + 4653 ) + 3145
    = 10000 + 10000 + 3145
    = 23145
    e) 2376 + 3425 – 376 – 425
    = ( 2376 – 376 ) + ( 3425 – 425 )
    = 2000 + 3000
    = 5000
    g) 3145 – 246 + 2347 – 145 + 4246 – 347
    = ( 3145 – 145 ) + ( 4246 – 246 ) + ( 2347 – 347 )
    = 3000 + 4000 + 2000
    = 9000
