Question

Formula in Excel starts with

• A. +
• B. -
• C. Excel data analysis tools
• D. =

Hint:

Although Excel allows you to start a formula with a plus (+) or minus (-) sign for compatibility with older legacy spreadsheet programs like Lotus 1-2-3, Excel automatically inserts an equals sign (=) in front of it once you press Enter.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Spreadsheet programs like Microsoft Excel distinguish between static data (text or numbers) and dynamic mathematical calculations (formulas) using specific start characters.

Step 3: Detailed Explanation:
In Microsoft Excel, a formula is an expression that calculates the value of a cell.
To tell Excel to evaluate a cell's contents as a mathematical formula rather than treating it as plain text, the entry must begin with an equals sign (\(=\)):
- When you type an equals sign, Excel's calculation engine is activated.
- This activation allows you to use mathematical operators (such as +, -, *, /), cell references (e.g., \(A_1 + B_2\)), and built-in functions (such as SUM, AVERAGE, or VLOOKUP).
- If you enter a formula like \(10 + 5\) without the leading equals sign, Excel treats it as a static text string and displays "10 + 5" in the cell.
- Entering \(=10 + 5\) tells Excel to calculate the expression and display the result, "15".
Therefore, all formulas in Excel must start with an equals sign.

Step 4: Final Answer:
Every formula in Excel must begin with the equals sign (=), matching Option (D).
