Explanation:
The explanation of the given question as follows:
- In question, it is defined that four cells that are "A1, A2, A3, and A4" contains value that are "10, 20, 30, and 40".
- To add these values we use addition formula that is "=A1+A2+A3+A4". it will give value 100.
- If the user inserts a new row that is "A2" and assigns a value in the cell that is "50" so, we use the above formula that adds values with these values we also use the value "100".
