Can anyone solve my question with step by step method pleaseeeeee?!!!!!!

Question 3 all parts

Answer 1

Hey mate !!

Here's your answer !!

Evaluate :



(a)  { ( - 6 ) * ( - 18 ) } * 12

We know that ,

( - ) * ( - ) = ( + )

So,

= { - 6 * - 18 } * 12

= 108 * 12

= 1296



(b) { ( -18 ) - ( + 12 ) } + 9

We know that,

( - ) - ( + ) = ( - )

So,

= { -18 - 12 ) + 9

= - 30 + 9

= ( - 21 )



(c) -16 ( - 14 - 12 ) + 10

= - 16 ( - 26 ) + 10

= + 416 + 10

= 426



( d ) - 18 + ( 1 * 9 + 9 * 1 )

= - 18 + ( 9 + 9 )

= - 18 + 18

= 0



Hope my answer helped you mate !!

Cheers !!

Answer 2

3.a. (-6×-18)×12
=108×12
=1296

3.b. {-18-(12)}+9
=-30+9
=-21

3.c. -16(-26)+10
=416+10
=426

3.d. -18÷18
=0
