How will the result be different between =PRODUCT($A6,B6) and =PRODUCT($A$6,B6) when either formula is copied down a given column?
The two formulas will provide the same result, there is no difference.
The formula =PRODUCT($A6,B6) will always multiply by the absolute value of Cell A6.
The formula =PRODUCT($A$6,B6) will always multiply by the absolute value of Cell A6.
The two formulas would produce the same value when copied down a column. They would produce a different value when copied across a row.

The correct answer and explanation is :

Correct Answer: The formula =PRODUCT($A$6,B6) will always multiply by the absolute value of Cell A6.

Detailed Explanation:

In Microsoft Excel, when you copy a formula from one cell to another, cell references can change unless they are specifically fixed. This behavior is known as relative referencing, and understanding how absolute and mixed references work is key to this question.

Let’s break down both formulas:

1. =PRODUCT($A6,B6)

  • $A6 is a mixed reference:
  • The column A is fixed (due to the dollar sign), so when copied across columns (e.g., to the right), the reference will stay in column A.
  • The row 6 is relative, so when copied down (e.g., to row 7), the row reference will change accordingly to A7, A8, etc.
  • B6 is a relative reference, so both row and column can change when copied.

Result when copied down: $A6 becomes $A7, $A8, etc., and B6 becomes B7, B8, etc., so the formula will compute A7*B7, A8*B8, etc.

2. =PRODUCT($A$6,B6)

  • $A$6 is an absolute reference, meaning both the column A and row 6 will not change, no matter where the formula is copied.
  • B6 is still a relative reference.

Result when copied down: $A$6 always refers to cell A6, while B6 becomes B7, B8, etc. So it computes A6*B7, A6*B8, and so on.

Summary of Differences:

  • =PRODUCT($A6,B6) changes the row number of A (A6 → A7) as it’s copied down.
  • =PRODUCT($A$6,B6) keeps A6 fixed regardless of how far down it’s copied.

Why the Correct Answer Is Right:

The phrase “absolute value of Cell A6” in the answer refers not to the mathematical absolute value (like |A6|), but to absolute referencing. Therefore, =PRODUCT($A$6,B6) always multiplies by the value in cell A6, making the answer correct.
