1. ( 17 x ( -13 )) - (( -75 ) : 5 )
= -221 - ( -15 )
= -221 + 15
= -206

2. 45 - ( -15 ) + (( -12 ) x 15 )
= 45 + 15 + ( -180 )
= 60 - 180
= -120

3. -50 + ( 42 : 6 ) - ( -30 )
= -50 + 7 + 30
= -43 + 30
= -13

4. ( -84 : 7 ) - (( -11 ) x 14 )
= -12 - ( -154 )
= -12 + 154
= 142

5. -35 + (( -18 ) x ( -12 )) - 45
= -35 + 216 - 45
= 181 - 45
= 136

6. 25 - ( -45 ) - ( 60 : ( -12 ))
= 25 + 45 - ( -5 )
= 70 + 5
= 75

7. 35 - 55 + (( -22 ) x 15 )
= -20 + ( -330 )
= -20 - 330
= -350

8. -60 - ( -25 ) + ( 90 : ( -6 ))
= -60 + 25 + ( -15 )
= -35 - 15
= -50

9. ( 18 x ( - 12 )) - 14 + ( -40 )
= -216 - 14 - 40
= -230 - 40
= -270

10. ( -70 : 5 ) + (( -17 ) x ( -13 ))
= -14 + 221
= 207
