Sheet Trace Quiz - 3 Questions
Test your understanding
What value does $A1 refer to when the formula is in cell B1?
AValue in A2
BValue in B1
CValue in A1
DValue in B2
Key Result
Mixed references fix either the column or the row, allowing partial locking of cell references.

Practice

(1/5)
1. What does the mixed reference $A1 mean in Excel?
easy
A. Neither the column nor the row is fixed; both change when copied.
B. The row 1 is fixed, but the column letter changes when copied.
C. Both the column and row are fixed and do not change when copied.
D. The column A is fixed, but the row number changes when copied.

Solution

  1. Step 1: Understand the $ symbol before the column letter

    The $ before A means the column A is fixed and will not change when the formula is copied across columns.

  2. Step 2: Understand the absence of $ before the row number

    The row number 1 is not fixed, so it will change when the formula is copied across rows.

  3. Final Answer:

    The column A is fixed, but the row number changes when copied. -> Option D

  4. Quick Check:

    Mixed reference $A1 fixes column only [OK]
Hint: Dollar before column fixes column; before row fixes row [OK]
Common Mistakes:
  • Thinking $A1 fixes the row instead of the column
  • Confusing $A1 with A$1
  • Assuming both row and column are fixed
2. Which of the following is the correct syntax for a mixed reference that fixes the row 5 but allows the column to change?
easy
A. $5A
B. A$5
C. $A$5
D. 5$A

Solution

  1. Step 1: Identify the correct placement of $ for fixing row

    To fix the row 5, the $ must be placed before the row number: A$5.

  2. Step 2: Check the options for correct syntax

    A$5 uses A$5 which fixes row 5 and allows column to change. Other options have incorrect order or fix both row and column.

  3. Final Answer:

    A$5 -> Option B

  4. Quick Check:

    Row fixed with $ before number = A$5 [OK]
Hint: Put $ before row number to fix row, before column letter to fix column [OK]
Common Mistakes:
  • Placing $ after the row number
  • Swapping column letter and row number
  • Using $ before both column and row when only one should be fixed
3. If cell B2 contains the formula = $A1 + A$1 and you copy this formula to cell C3, what will be the resulting formula in C3?
medium
A. = $B2 + B$2
B. = $A3 + C$1
C. = $A2 + B$1
D. = $A3 + B$1

Solution

  1. Step 1: Analyze the $A1 part when copied from B2 to C3

    $ before A fixes the column A, so column stays A. Row 1 changes relative to row move: from row 2 to 3 is +1, so row 1 becomes 2. So $A1 becomes $A2.

  2. Step 2: Analyze the A$1 part when copied from B2 to C3

    $ before 1 fixes the row 1, so row stays 1. Column A changes relative to column move: from B to C is +1, so A becomes B. So A$1 becomes B$1.

  3. Final Answer:

    = $A2 + B$1 -> Option C

  4. Quick Check:

    Fixed column stays, fixed row stays, others shift [OK]
Hint: Fixed parts stay; unfixed parts shift with copy [OK]
Common Mistakes:
  • Changing fixed column or row incorrectly
  • Not adjusting relative parts when copying
  • Mixing up column letters and row numbers
4. You have a formula in cell D4: =SUM($B2:B$5). When copying this formula to cell E6, the formula becomes =SUM($B4:C$5). Is this correct? If not, what is the correct formula?
medium
A. =SUM($B4:C$5)
B. =SUM($B4:B$5)
C. =SUM($B4:C$7)
D. =SUM($B2:C$7)

Solution

  1. Step 1: Trace the start reference $B2 from D4 to E6

    Copy is +1 column (D->E), +2 rows (4->6). $B fixes column B; row 2 relative +2 -> $B4.

  2. Step 2: Trace the end reference B$5

    Column B relative +1 -> C; $5 fixes row 5 -> C$5.

  3. Step 3: Resulting formula is =SUM($B4:C$5)

    This matches the formula stated in the question, confirming it is correct.

  4. Final Answer:

    =SUM($B4:C$5) -> Option A

  5. Quick Check:

    $B2:B$5 -> $B4:C$5 (+1col +2row) [OK]
Hint: Shift relative parts by copy distance; fixed parts stay [OK]
Common Mistakes:
  • Not shifting row or column correctly
  • Assuming fixed parts change
  • Miscalculating relative shifts for range endpoints
5. You want to create a formula in cell B2 that multiplies the value in column A of the same row by the value in row 1 of the same column, and then copy it across columns and rows. Which mixed reference formula should you use in B2?
hard
A. = $A2 * B$1
B. = A$2 * $B1
C. = $A$2 * $B$1
D. = A2 * B1

Solution

  1. Step 1: Fix the column for the value in column A but allow row to change

    The value in column A of the same row means column A fixed ($A), row relative (2). So use $A2.

  2. Step 2: Fix the row for the value in row 1 but allow column to change

    The value in row 1 of the same column means row 1 fixed ($1), column relative (B). So use B$1.

  3. Step 3: Combine both parts in multiplication formula

    The formula is = $A2 * B$1, which will adjust correctly when copied across rows and columns.

  4. Final Answer:

    = $A2 * B$1 -> Option A

  5. Quick Check:

    Fix column for first, fix row for second [OK]
Hint: Fix column for vertical, fix row for horizontal references [OK]
Common Mistakes:
  • Fixing both row and column unnecessarily
  • Not fixing any part causing wrong references
  • Swapping fixed parts between references
