Always follow the BODMAS sequence strictly: First divide 9 by 6 to get 1.5, then multiply by 6 to get 9, and finally subtract from 38.
An arithmetic expression: 38 - 9 ÷ 6 × 6
BODMAS:Brackets, Of, Division, Multiplication, Addition, Subtraction
Always follow the BODMAS sequence strictly: First divide 9 by 6 to get 1.5, then multiply by 6 to get 9, and finally subtract from 38.
Students often perform multiplication before division (left to right) because they confuse the sequence, calculating 9 ÷ (6 × 6) = 0.25, which is incorrect.
Division step
According to the BODMAS rule, division comes before multiplication. So, divide 9 by 6 first: 9÷6=1.5.
9÷6=1.5
Multiplication step
Now multiply the result by 6: 1.5×6=9.
1.5×6=9
Subtraction step
Finally, perform the subtraction from 38: 38−9=29.
38−9=29
A is correct because applying the BODMAS order of operations yields a final result of 29.
The BODMAS rule is universal; consistently apply it in algebra and physics numericals to avoid calculation errors in complex equations.
