(i) (-6) + (-9) * (-6) – (-9)
(ii) (-12) – (-12) * (-12) + (-12)
(iii) (-20) – (-20) * 20 - (65)
(iv) 28 – (-10) * (-16) – (-76) ​

Answer 1

Answer:

Step-by-step explanation:

( i )

( - 6 ) + ( - 9 ) * ( - 6 ) - ( - 9 )

= ( - 6 ) + 54 - ( - 9 )

= - 6 + 54 + 9

= 57

( ii )

( - 12 ) - ( - 12 ) * ( - 12 ) + ( - 12 )

= - 12 - 144 - 12

= - 168

( iii )

( - 20 ) - ( - 20 ) * 20 - ( 65 )

= - 20 - ( - 400 ) - 65

= - 20 + 400 - 65

= 315

( iv )

28 - ( - 10 ) * ( - 16 ) - ( - 76 )

= 28 - 160 + 76

= - 56 ​
