Evaluate division and multiplication strictly from left to right, then compute independent multiplication products before final subtraction.
An arithmetic expression involving division, multiplication, and subtraction: 48 ├╖ 8 ├Ч 4 - 3 ├Ч 5
Result=(48├╖8├Ч4)тИТ(3├Ч5)
Evaluate division and multiplication strictly from left to right, then compute independent multiplication products before final subtraction.
Performing multiplication before division or doing subtraction before multiplication, which alters the order of operations.
Step 1: Perform Division
According to the BODMAS rule, division and multiplication have equal precedence and are evaluated from left to right. First, compute 48├╖8.
48├╖8=6
Step 2: Perform Multiplication
Next, multiply the result by 4, and simultaneously evaluate the independent multiplication term 3├Ч5.
6├Ч4=24,3├Ч5=15
Step 3: Perform Subtraction
Substitute these values back into the expression to perform the final subtraction: 24тИТ15.
24тИТ15=9
A is correct because evaluating the expression step-by-step using the BODMAS rule yields 9.
Mastering the order of operations is crucial for solving algebraic equations and data interpretation problems accurately in competitive exams.
