if so, then it would be:
\(6\cdot 3\cdot [-9+4(5\cdot 3-9)]-3\cdot (40-8)\)
(calculate parenthesis) \(\left[-9+4\left(5\cdot3-9\right)\right]=15\)
\(6\cdot3\cdot15-3\left(40-8\right)\)
(calculate parenthesis) \((40-2)=38\)
\(6\cdot3\cdot15-3\cdot32 \)
(multiplication) \(6\cdot3\cdot15=270\)
\(270-3\cdot32\)
(multiplication) \(3\cdot32=96\)
\(270-96=174\)
