Use the BODMAS rule strictly: first solve the bracket, then multiply, then perform subtraction from left to right to save time.
The expression provided is 110 - 42 * (5 + 6) - 6.
BODMAS=(Brackets,Orders,Division,Multiplication,Addition,Subtraction)
Use the BODMAS rule strictly: first solve the bracket, then multiply, then perform subtraction from left to right to save time.
Students often make a mistake by performing subtraction before multiplication, violating the priority order of BODMAS.
Step 1: Solve the Bracket
According to BODMAS, solve the part inside the bracket first: (5+6)=11.
110−42×11−6
Step 2: Multiplication
Perform the multiplication 42×11. 42×11=462.
110−462−6
Step 3: Final Subtraction
Subtract the remaining numbers from left to right: 110−462=−352, then −352−6=−358.
110−462−6=−358
D is correct because the step-by-step application of the BODMAS rule results in -358.
Mastering BODMAS is foundational for simplification questions in Quantitative Aptitude; always process signs with care when dealing with multiple subtractions.
