assignment operator, relational operators, logical or Boolean operators.

2. / (Division) operator is used to divide the numbers and give an output in the decimal
form, e.g., Value of 5/2 is 2.5. whereas, // (Floor Division) divides the numbers and gives
an output in the integer form, e.g., Value of 5//2 is 2.

3. *' operator in a string manipulation is used to replicate a given string for a number of
times. It is also known as Replication Operator.

4. The Logical or Boolean operators are used to compare two or more expressions, and
evaluate to either True or False. Relational operators compare the values of the
variables and determine the result in a boolean expression either 'True' or 'False'.

5. The different types of control structures are Sequential statements, Conditional
statements, and Iterative statements.

6. The conditional statements cause the program control to transfer to a specific location
depending on the outcome of the conditional expression. The syntax of if statement is:
if <condition>:

in data over a period of time, However, Bar chart helps to display the data in the form of
bars horizontally or vertically. It displays comparison amongst the individual items.

3. The Chart area includes all the objects and elements in a chart. Plot area is a window
within a Chart area. It contains the actual chart and includes the plotted data, data
series, and category and value axis.

4. Grouping worksheets facilitates in editing multiple worksheets at the same time. By
grouping worksheets, you can enter common data, formatting effects, and formulas in
the grouped sheets.

5. Consolidation helps in combining the data of multiple worksheets. We can combine data
of various ranges either in the same sheet or in different sheets.

6. Sparklines are mini charts that fit into a single worksheet cell to provide a visual
representation of the data. These can be used to analyse the trends in your data. There
are three types of sparklines—Line, Column, and Win/Loss.

2. The cell address in a formula is known as the cell reference. References help in
finding the values or data in a worksheet, that you want to use in formula. Types of
cell references: Relative reference, Absolute reference, and Mixed reference.

3. Absolute reference is used when it is required to keep the address of the cell fixed
while copying the formula to another cell. To use absolute reference in a formula,
dollar sign ($) is used before the column and row number. Example: =$A$1+$A$2

4. 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. Some examples are: SUM, AVERAGE, ODD, ROUND, etc.

5. The Concat() function is used to join two or more than two strings together.
Whereas, Textjoin() lets you join the text specified in a range of cells where you can
add words and a delimiter you specify between each text value.

2) Write down the remainder
and divide the quotient again by 2.

3) Repeat the step 2 till the quotient is zero.

3. The concept of Octal numbers system came from the Native American. The Octal
number system consists of 8 digits: 0 to 7 with base 8.

4. A computer understands only the binary codes. Therefore, the data that is entered
into a computer is converted into its binary equivalent. It further converts the binary
results into their decimal equivalents for the output.
