📊 Formula Result

What is the result of this formula after editing the cell?

You have entered the formula =A1+B1 in cell C1. Cell A1 contains 5 and cell B1 contains 3. You then edit cell B1 and change its value to 7. What is the new value displayed in cell C1?

A 12

B 8

C 5

D 7

💡 Hint

Remember that formulas update automatically when referenced cells change.

The formula =A1+B1 adds the values in A1 and B1. When B1 changes from 3 to 7, the formula recalculates as 5 + 7 = 12.

❓ Function Choice

How many cells contain data after these edits?

You start with an empty worksheet. You enter data in cells A1, B1, and C1. Then you delete the content in B1. How many cells contain data now?

A 0

B 2

C 1

D 3

💡 Hint

Deleting content removes data from that cell.

Initially, 3 cells have data. After deleting B1's content, only A1 and C1 contain data, so 2 cells remain filled.

📊 Formula Result

What is the displayed value after entering this formula with mixed data?

Cell A1 contains the text '10', cell B1 contains the number 5. You enter the formula =A1+B1 in cell C1. What is the result shown in C1?

A 105

B 10

C 15

D #VALUE!

💡 Hint

Excel tries to convert text to numbers when possible in formulas.

Excel converts the text '10' in A1 to the number 10 and adds it to 5, resulting in 15.

Practice

1. What happens when you click a cell in Excel and start typing?

easy

A. The typed data is ignored until you press Enter.

B. The typed data replaces any existing content in that cell.

C. Excel opens a new worksheet for the typed data.

D. The typed data is added to the end of the existing content.

Solution

   Clicking a cell selects it and typing immediately replaces any existing content.

2. Step 2: Confirm behavior on typing

   Typing overwrites the current cell content unless you enter edit mode first.

3. Final Answer:

   The typed data replaces any existing content in that cell. -> Option B

4. Quick Check:

   Click + type = replace content [OK]

Hint: Click cell and type to replace content immediately [OK]

Common Mistakes:

• Thinking typing adds to existing content without editing
• Believing Excel opens a new sheet automatically
• Assuming data is ignored until Enter is pressed

2. Which method allows you to edit the content of a cell without deleting it first?

3. Final Answer:

   The word 'Hello' is saved in A1 and the selection moves to cell A2. -> Option A

4. Quick Check:

   Enter saves + moves down [OK]

Hint: Press Enter to save and move down one cell [OK]

Common Mistakes:

• Thinking selection stays on the same cell
• Assuming selection moves right instead of down
• Believing data isn't saved until clicking elsewhere
