What is the output of the formula when copied?

You have the formula =A1+B1 in cell C1. If you copy this formula from C1 to C2, what will be the formula in C2 and what will it calculate if A2=3 and B2=4?

A Formula in C2: <code>=A2+B2</code>, Result: 7

B Formula in C2: <code>=A1+B1</code>, Result: 5

C Formula in C2: <code>=B2+A2</code>, Result: 7

D Formula in C2: <code>=C1+B1</code>, Result: 9

💡 Hint

Think about how relative references change when you copy formulas down a row.

Relative references adjust based on the position where the formula is copied. Copying from C1 to C2 shifts the references from A1 and B1 to A2 and B2, so the formula becomes =A2+B2 and calculates 3+4=7.

❓ Function Choice

intermediate

Which formula correctly sums the values in the row when copied?

You want to sum values in columns A and B for each row starting from row 2. Which formula should you put in cell C2 so that when copied down, it sums the correct row's A and B values?

A =SUM($A2:$B2)

B =SUM($A$2:$B$2)

C =SUM(A$2:B$2)

D =SUM(A2:B2)

💡 Hint

Consider how relative and absolute references behave when copying formulas down rows.

Using =SUM(A2:B2) with relative references allows the formula to adjust to each row when copied down, summing the correct cells in columns A and B for that row.

🎯 Scenario

Fix the formula to keep column fixed but allow row to change when copied

You have the formula =A1*B1 in cell C1. You want to copy it down column C so that the reference to column A stays fixed but the row number changes (A1, A2, A3, ...). Which formula achieves this?

A =$A$1*B1

B =A$1*B1

C =$A1*B1

D =A1*$B1

💡 Hint

Use $ to fix the column but leave the row relative.

Using $ before the column letter fixes the column (A), while leaving the row number relative allows it to change when copied down. So =$A1*B1 fixes column A but changes row.

How many cells will show the value 10 after copying the formula?

In cells A1 to A5, the values are 2, 4, 6, 8, 10 respectively. In cell B1, you enter the formula =A1*5 and copy it down to B5. How many cells in B1:B5 will show the value 10?

A 1

B 2

C 0

D 5

💡 Hint

Multiply each A cell by 5 and check which equals 10.

Only A1=2 multiplied by 5 equals 10, so only B1 shows 10.

What is the value in cell C3 after copying the formula?

You have the formula =SUM(A1:B1) in cell C1. You copy this formula down to C3. Given the following values:
A1=1, B1=2
A2=3, B2=4
A3=5, B3=6
What is the value in cell C3?

A 5

B 11

C 7

D 3

💡 Hint

Check how the relative references change when copying down two rows.

Copying the formula from C1 to C3 shifts the references from A1:B1 to A3:B3. Sum of A3 and B3 is 5+6=11.

Practice

1. What happens to a relative cell reference like A1 when you copy a formula from cell B1 to cell B2 in Google Sheets?

easy

A. It becomes an error because references cannot change.

B. It stays as A1 because it is fixed.

C. It changes to A2 to match the new row.

D. It changes to B1 to match the new column.

Solution

1. Step 1: Understand relative references behavior

   Relative references adjust based on the position where the formula is copied. Copying down one row changes the row number in the reference.

2. Step 2: Apply to the example

   Copying a formula from B1 to B2 moves it down one row, so A1 becomes A2.

3. Final Answer:

   It changes to A2 to match the new row. -> Option C

4. Quick Check:

   Relative reference row changes when copied down [OK]

Hint: Relative references adjust row/column based on copy direction [OK]

Common Mistakes:

• Thinking relative references stay fixed
• Confusing relative with absolute references
• Assuming column changes when copying down

2. Which of the following is the correct way to write a relative reference to cell C3 in a formula?

easy

A. C3

B. C$3

C. $C$3

D. $C3

Solution

1. Step 1: Identify relative vs absolute references

   Relative references have no dollar signs and change when copied. Absolute references use $ to fix row, column, or both.

2. Step 2: Check each option

   C3 is C3 with no $ signs, so it is fully relative.

3. Final Answer:

   C3 -> Option A

4. Quick Check:

   No $ means relative reference [OK]

Hint: No $ means relative reference in formulas [OK]

Common Mistakes:

• Using $ signs thinking they are needed for relative
• Mixing absolute and relative incorrectly
• Confusing syntax of $ for fixing references

3. If cell B2 contains the formula =A1+1 and you copy this formula to cell B3, what will be the formula in B3 and its result if A2=5?

medium

A. Formula: =A3+1, Result: 7

B. Formula: =A1+1, Result: 2

C. Formula: =B2+1, Result: 3

D. Formula: =A2+1, Result: 6

Solution

1. Step 1: Understand how relative references adjust when copied down

   Copying the formula from B2 to B3 moves it down one row, so A1 becomes A2.

2. Step 2: Calculate the result using A2=5

   The formula in B3 is =A2+1, so the result is 5 + 1 = 6.

3. Final Answer:

   Formula: =A2+1, Result: 6 -> Option D

4. Quick Check:

   Relative reference row updates, result matches calculation [OK]

Hint: Copying down changes row number in relative references [OK]

Common Mistakes:

• Not updating the row number in the reference
• Confusing column changes when copying down
• Calculating result without updating reference

4. You have a formula in cell C3: =A1+B1. When you copy it to cell C4, the formula becomes =A2+B2. But you want it to stay =A1+B1. What is the best fix?

medium

A. Change the formula to =A$1+B$1

B. Change the formula to =$A$1+$B$1

C. Change the formula to =A1+B1 again

D. Change the formula to =A2+B2

Solution

1. Step 1: Identify why formula changes when copied

   Relative references like A1 change when copied. To keep them fixed, use absolute references with $.

2. Step 2: Use absolute references to fix both row and column

   Using $A$1 and $B$1 fixes both row and column, so the formula stays the same when copied.

3. Final Answer:

   Change the formula to =$A$1+$B$1 -> Option B

4. Quick Check:

   Absolute references keep formula fixed when copied [OK]

Hint: Use $ before column and row to fix references [OK]

Common Mistakes:

• Using partial absolute references that don't fix both row and column
• Not using $ at all
• Trying to copy formula without fixing references

5. You have a list of prices in column A (A2:A6) and want to calculate a 10% tax for each price in column B using a formula in B2 copied down. Which formula correctly uses relative references to calculate tax for each row?

hard

A. =A2*0.10

B. =A$2*0.10

C. =$A2*0.10

D. =$A$2*0.10

Solution

1. Step 1: Understand the need for relative reference in row

   Each row in column B should multiply the price in the same row of column A. So the row number must change when copied down.

2. Step 2: Check which formula allows row to change

   =A2*0.10 uses A2 without $, so row changes when copied. Options A, C, D fix either row or column incorrectly.

3. Final Answer:

   =A2*0.10 -> Option A

4. Quick Check:

   Relative row reference changes per row [OK]

Hint: Use relative row to apply formula to each row correctly [OK]

Common Mistakes:

• Fixing row with $ so tax is same for all rows
• Fixing column unnecessarily
• Using absolute references that don't update per row
