  1. 35 x 34 + 3
    = 1190 + 3
    = 1193
       
    50 x 67 + 5 
     = 3350 + 5 
    = 3355 
       
    42 + 78 x 4
    = 42 + 312
    = 354 
    86 – 12 x 51
    = 86 – 612
     = – 526

  2. $\text{25 x 34 + 3}$
    $\text{= 850 + 3}$
    $\text{= 853}$
    $\text{50 x 67 + 5}$
    $\text{= 3350 + 5}$
    $\text{= 3355}$
    $\text{42 + 78 x 4}$
    $\text{= 42 + 312}$
    $\text{= 354}$
    $\text{86 – 12 x 51}$
    $\text{= 86 – 612}$
    $\text{= -526}$
