  1. 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 × 0 × 0 – 12 – 13 – 14 – 17 – 18 – 100
    = ( 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 ) + ( 1 × 0 × 0 ) – ( 12 + 13 + 14 + 17 + 18 + 100 )
    = 9 + 0 – 174
    = 9 – 174
    = -165

  2. 1+1+1+1+1+1+1+1+1+1 xx 0 xx 0 -12 -13-14-17-18-100
    =(1+1+1+1+1+1+1+1+1)+(1 xx 0 xx 0) -(12+18)-(13+17)-(14+100)
    =9-30-30-114
    =9-60-114 
    =-165
