The correct choice is to use the SUM function in a formula to add the three cells. This is because the SUM function is a built-in spreadsheet tool specifically designed to total a range of values, such as a row of cells, without requiring manual addition. By entering a formula like =SUM(A2:C2), the assistant can automatically calculate the total of the previous three columns for each row, eliminating the risk of human error and ensuring efficiency. On the CompTIA ITF+ FC0-U61 exam, this scenario tests your understanding of basic spreadsheet functions and formula syntax, often appearing in questions about automating calculations for business reports. A common trap is confusing SUM with the AVERAGE or COUNT functions, which serve different purposes. Remember the memory tip: “SUM adds it all up”—think of the word “sum” as “total” to quickly recall its role in summing columns or rows.
FC0-U61 Applications and Software Practice Question
This FC0-U61 practice question tests your understanding of applications and software. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An administrative assistant is using a spreadsheet application to create a budget report. The assistant needs to add a column that calculates the total of the previous three columns for each row. The assistant is not very experienced with formulas and is unsure how to proceed. The assistant wants to use a built-in function that will automatically sum the values. Which of the following should the assistant do to achieve this?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use the SUM function in a formula to add the three cells.
The SUM function is the correct built-in function in spreadsheet applications (like Microsoft Excel or Google Sheets) to add a range of cells. By using a formula such as =SUM(A2:C2), the assistant can automatically calculate the total of the three columns for each row without manual errors. This directly meets the requirement to sum values efficiently.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Manually type each cell reference separated by plus signs.
Why it's wrong here
Manual entry is possible but not efficient and prone to errors.
✗
Use the COUNT function to count the number of cells.
Why it's wrong here
COUNT counts cells, but does not sum values.
✗
Use the AVERAGE function to find the average of the values.
Why it's wrong here
AVERAGE calculates the mean, not the total.
✓
Use the SUM function in a formula to add the three cells.
Why this is correct
SUM is designed to add numerical values.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may confuse the SUM function with other aggregate functions like COUNT or AVERAGE, or assume manual addition is acceptable, but the question specifically requires a built-in function for automatic summation.
Detailed technical explanation
How to think about this question
The SUM function in spreadsheet software accepts a range of cells (e.g., SUM(A2:C2)) or individual arguments, and it automatically handles empty cells or non-numeric entries by ignoring them, unlike manual addition which may cause errors. Under the hood, the function iterates over the specified range and accumulates numeric values, making it both efficient and robust for budget reports. In real-world scenarios, using SUM with named ranges or structured references (e.g., =SUM(Table1[Column1]:[Column3])) can further simplify maintenance as data grows.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the FC0-U61 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
