What will be the output of the following formula in MS-Excel 2010? =9/6*4+4-1

Appeared in: NHM UP Staff Nurse-2023 shift 1st

Explanation

The formula is evaluated using the BODMAS/PEMDAS rule for the order of operations.
Multiplication and Division have higher precedence than Addition and Subtraction.
Operations with the same precedence (like Division and Multiplication) are evaluated from left to right.
First, 9 is divided by 6, resulting in 1.5.
Next, 1.5 is multiplied by 4, resulting in 6.
Then, 6 is added to 4, resulting in 10.

Option A: This result is incorrect. It would be obtained if the order of operations was not followed correctly.
Option B: This is an incorrect result. It arises from misinterpreting the left-to-right rule for operators of the same precedence.
Option D: This result is incorrect. It might occur if addition or subtraction were performed before multiplication or division, which violates the BODMAS/PEMDAS rule.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Order of operations (BODMAS/PEMDAS) in MS-Excel formulas as background academic context rather than a clinical decision trigger.
While not a clinical question, proficiency in MS-Excel is a valuable skill for nurses.
Nurses use spreadsheets for managing patient data, creating staff schedules, tracking inventory of medical supplies, and documenting research data.
Understanding how formulas work is crucial for accurate data analysis, such as calculating patient trends, medication dosages, or budget reports for a nursing unit.

How to Approach the Question

First, read the formula carefully: =9/6*4+4-1.
Recall the order of operations: PEMDAS/BODMAS (Parentheses/Brackets, Exponents/Orders, Multiplication/Division, Addition/Subtraction).
Scan the formula for parentheses and exponents. There are none.
Identify the multiplication and division operators. Evaluate them from left to right: 9/6 first, then multiply the result by 4.
Identify the addition and subtraction operators. Evaluate them from left to right: add 4 to the previous result, then subtract 1.
Perform the calculations step-by-step to arrive at the final answer and select the matching option.
