  1. Giải đáp:
     
    Lời giải và giải thích chi tiết:
    a 382+531-282-331
    =(382-282)+(531-331)
    =100+200
    =300. 
    b 4573+46-4573+35-16-5
    =(4573-4573)+(46-16)+(35-5)
    =0+30+30
    =60.
    c 32+34+36=38-10-12-14-16-18
    =(32-12)+(34-14)+(36-16)+(38-18)-16
    =20+20+20+20-16
    =20 x 4-16
    =80-16
    =64.

  2. $382+531-282-331$
    $=(382-282)+(531-331)$
    $=100+200$
    $=300$

    $b) 4573+46-4573+35-16-5$
    $=(4573-4573)+(46-16)+(35-5)$
    $=30+30$
    $=60$

    $c) 32+34+36=38-10-12-14-16-18$
    $=38-10-12-14-16-18-32-34-36$

    $=-32$
