The correct answer is
-322
-322 is correct.
Follow BODMAS: brackets from the innermost outward, and inside each bracket division before subtraction.
Innermost bracket first: \(300\div 12=25\) and \(35-25=10\).
Then \(10\div 10=1\) and \(90\div 10-1=9-1=8\).
Next \(450-8=442\), and finally \(120-442=-322\).
