Simplify \( \Large 6-\left[ 9-\{18- \left(15-\overline{12-9}\right) \} \right] \)

A) 1
B) 4
C) 5
D) 3

Correct Answer:




D) 3

Description for Correct answer:
Given expression

=\( \Large 6-\left[ 9-\{ 18- \left(15-\overline{12-9}\right) \} \right] \)

=\( \Large 6-\left[ 9-\{ 18- \left(15-12+9\right) \} \right] \)

=\( \Large 6-\left[ 9-\{ 18-12 \} \right] \)

=\( \Large 6-\left[ 9-6 \right] = 6-3 = 3 \)
