  1. 65 × 119 + 47 × 119 – 19 × 112
    =(65 × 119) + (47 × 119) – (19 × 112)
    =7735 + 5593 – 2128
    =11200
     

  2. Giải:
    65 xx 119 + 47 xx 119 – 19 xx 112
    = (65 + 47) xx 119 – 19 xx 112
    = 112 xx 119 – 19 xx 112
    = 112 xx (119 – 19)
    = 112 xx 100
    = 11200
    Giải đáp: 11200
