Step-by-step explanation:
= 40 + [ 3 { 18 ÷ ( 9 - 3 ) - 11 - 9 } + 4 ]
= 40 + [ 3 { 18 ÷ 6 - 11 - 9 } + 4
= 40 + [ 3 { 3 - 20 } + 4
= 40 + [ 3 {- 17 } + 4
= 40 + ( - 51 ) + 4
= 40 + 4 - 51
= 44 - 51
= - 7

Answer:
[tex] \sf \large \: - 7[/tex]
40+3(18/9−3−11−9)+4
=40+3(18/6−11−9)+4
=40+3(3−11−9)+4
=40+3(−8−9)+4
=40+(3)(−17)+4
=40+−51+4
=40+−47
=−7
