1. Formulas are used to perform calculations.
2. The cell address in a formula is also called cell reference.
3. The cell address in a formula that doesn’t change on copying is considered as absolute reference.
4. Arguments are input to functions which accept values as number or text.
5. The & character is used for concatenation of strings.

B. State True or False:
1. Formulas must begin with the question mark (?). (False)
Formulas must begin with the equal to (=).
2. In Absolute Referencing, the relative position of rows and columns changes where you copy a formula. (False)
In Absolute Referencing, the relative position of rows and columns doesn’t changes where you copy a formula.
3. Excel has clubbed all the functions in the Formulas Library group. (False)
Excel has clubbed all the functions in the Function Library group.
4. A range can be used in a formula. (True)
5. The error # VALUE occurs if the number is divided by zero. (False)
The error #DIV/0! occurs if the number is divided by zero.

C. Application Based Questions:
1. A Sports teacher has measured the height of the students in a class. Saumya has been given the assignment to find the maximum and minimum height of the students. Suggest the function, which she should use to accomplish the task.
Saumya can use MAX() function to find the maximum height and MIN() function to find the minimum height.

2. Ms Priya and her friends got a raise of 10% in their salaries. Find the total amount if the present salary is ₹15,000. Calculate the salary by using the formula.
15,000 + (15,000 × 10/100) = 16,500

D. Multiple Choice Questions:
1. To use the Sheet reference, which address is appropriate out of the following options?
a) D4! Sheet1
b) Sheet1, D4
c) Sheet1! D4
c) Sheet1! D4

2. Which key combination is used to get the sum of the values of adjacent cells?
a) Shift + S
b) Ctrl + '
c) Alt + =
c) Alt + =

3. Which function finds the largest number in a range?
a) AVERAGE()
b) COUNT()
c) MAX()
c) MAX()

4. Which of the given cell references can be used in a relative reference?
a) \$D6
b) A3
c) A\$1
b) A3

5. Which function is used to count the number of numeric values in a range?
a) COUNT()
b) SUM()
c) MAX()
a) COUNT()

1. What is a Formula? Explain with the help of an example.
Formulas are used to perform calculations involving addition, subtraction, division and multiplication etc. It is an expression that can include cell addresses, numbers, arithmetic operator, and parenthesis. We can perform simple calculations as well as complex calculations. Example: A1 + B1 + C1

2. What is Cell Reference? Mention its types.
The cell address that we use in the formula is known as cell reference. There are three types of cell references
a) Relative Reference
b) Absolute Reference
c) Mixed Reference

3. What do you know about Absolute Referencing? Explain with the help of an example.
Absolute Referencing is used when we don’t want to change the address of the cell on copying the formula to another cell. To make absolute reference of a formula, add a dollar sign (\$) before the column name and row name. Example: \$A\$1 + \$A\$2

4. What do you understand by the term Concatenation? Explain with the help of an example.
Addition of two or more text values is called Concatenation. Example: If we type a string value in cell A1 and B1, say “Dogs” in A1 and “Cats” in B1 and enter the formula = A1&B1 in cell C1, and press the Enter key. Then it will display “DogsCats” in cell C1.

5. What do you mean by a Function? Name some of the Functions.
Functions are the pre-designed formulas in Excel to perform both simple and complex calculations. Functions save time and eliminate the chance to write wrong formulas. They accept Arguments and return Values. Example: SUM(), AVERAGE(), MAX(), TODAY() etc.

6. What are the rules to enter a Function?
