  1. Giải đáp: 25 . 32 + 4. 92. 25
                = 800  + 9200
                 = 10000
       3119 . 121 – 3119 .  11 . 11
    = 377399 – 377399
    = 0
     24.( 123 + 87 ) + ( 87 + 123 ) . 76
    = 24 . 210         + 210 . 76
    =   5040 + 15960
    = 21000
     
     

  2. 25 . 32 + 4. 92. 25
    = 800  + 9200
    = 10000
    3119 . 121 – 3119 .  11 . 11
    = 377399 – 377399
    = 0
    24 . (123 + 87) + (87 + 123) . 76

    =24.210+210.76

    =210.(24+76)

    =210.100

    =21000
