Using bodmas rule
B - brackets.
O - of .
D - division.
M - multiplication.
A - addition.
S - subtraction.

= [ 20 - 2 { 5 + ( -12 )} × { 2 ( 5 - 2 - 4 )}]

= [ 20 - 2 { -7} × { 2 ( 5 - 6 )}]

= [ 20 - 2 { -7} × { 2 ( -1)}]

= [ 20 - 2 { -7} × { -2}]

= [ 20+14×-2]

=[20+(-28)]

=[20-28]

=> -8

hope it helps you

$<b>Answer:$

We will follow the BODMAS rule for solving this question:

B - brackets

O - of

D - division

M - multiplication

A - addition

S - subtraction

=============================

Main Solution:

[ 20 - 2 { 5 + ( -12 )} × { 2 ( 5 - 2 - 4 )}]

[ 20 - 2 { 5 + ( -12 )} × { 2 ( 5 - 6 )}]

[ 20 - 2 { 5 + ( -12 )} × { 2 ( -1)}]

[ 20 - 2 { 5 + ( -12 )} × { -2}]

[ 20 - 2 { -7} × { - 2}]

[ 20 - 2 × 14 ]

[ 20 - 28 ]

=> -8

Hence, the final answer is -8.
