Which function in a spreadsheet adds together a range of numbers?

• A. AVERAGE function
• B. SUM function
• C. COUNT function
• D. MAX function

Answer: (B)

The function that adds together a range of numbers in a spreadsheet is the SUM function. This function is specifically designed to calculate the total of all the numeric values within the specified range. It takes all the numbers included in that range and provides their total, making it a fundamental tool for performing basic arithmetic operations in spreadsheet applications.

In contrast, the AVERAGE function calculates the mean of a range of values, which is different from simply adding them together. The COUNT function serves to count the number of entries in a range, regardless of their numerical value, which does not involve any addition. Lastly, the MAX function identifies the highest value in a dataset, which again does not pertain to summing numbers. Therefore, when the task is to find the total of a set of numbers, the SUM function is the appropriate choice.
