QUESTION/DISCUSSION

1.HOW TO CREATE THE TABE.

In addition to its other spreadsheet features, Microsoft Excel offers you the ability to create tables within a spreadsheet. Known as “lists” in Excel 2003, they can be managed separately from data you have elsewhere on that spreadsheet page or any other page in the spreadsheet. See Step 1 below for instructions to make and manipulate tables in Microsoft Excel.

Part 1 of 8: Creating a Table

1Select a range of cells. The cells can contain data or they can be empty, or a combination of both. You don’t have to pick your cells before you create the table if you aren’t sure yet.

Page 3: Js02 Muhamad Hakimi Azali Bin Azlan

2Insert the table. To start the table creation process, you will need to insert a table into your spreadsheet.

In Excel 2003, click the Data menu and select List. In Excel 2007, 2010, and 2013 select either "Table" on the Insert menu ribbon or

"Format as Table" in the Styles group on the Home menu ribbon. (The former option applies Excel's default table style, while the other lets you choose a style when you create the table. You can later apply or change the table style by selecting one of the options from the Table Styles group in the Table Tools Design menu ribbon.) [1]

3Provide a data source for your table. If you did not previously select a group of cells, you will need to select the cells now. After you pick your range, a dialog box will appear, either the Create Table dialog (Create List dialog in Excel 2003) or the Format As Table dialog.

The "Where is the data for your table?" field displays the absolute reference(s) for the current cell(s) selected. If you want to change this information, you can type in a different cell or range reference.

4Indicate whether your table has headers. If your table has headers, check the "My table has headers" box. If you don't check this box, the table will display default header names ("Column 1," "Column 2," etc.).

You can change a column name by selecting the header and typing in your own name in the formula bar.

2.Give example for mathematics formula using excel.

On a worksheet, you can enter simple formulas to add, divide, multiply, and subtract two or more numeric values. You can also enter a formula that uses the SUM function (also known as AutoSum) to quickly total a series of values without having to enter any of them manually in a formula. Once you have created a formula, you can fill it into adjacent cells — no need to create the same formula over and over again.

When you become familiar with these simple formulas, you may want to learn more about how to create complex formulas and try some of the many functions that are available in Excel. For more information, see Overview of formulas and List of worksheet functions (by category).

Learn more about simple formulasThe first thing that you have to know is that all formula entries start with an equal sign (=). For simple formulas, you type the equal sign followed by the numeric values that you want to calculate and the math operators that you want to use — for example the plus sign (+) to add, the minus sign (-) to subtract, the asterisk (*) to multiply, and the forward slash (/) to divide the values that you enter. When you press ENTER, Excel instantly calculates and displays the result of the formula.

For example, when you type a simple formula in a cell (for example, =12.99+16.99 in cell C6 in the following picture) and then press ENTER, Excel calculates the result and displays it in that cell. The formula itself appears in the formula bar.

Page 7: Js02 Muhamad Hakimi Azali Bin Azlan

The formula that you enter in a cell remains visible in the formula bar, and you can see it whenever that cell is selected.

Click AutoSum, and voila!

To quickly total a series of values without having to enter any of them manually in a formula, you can enter a formula that uses the SUM function, also known as AutoSum.

AutoSum is the button that displays the "summation" symbol (the uppercase Sigma of the Greek alphabet). Within easy reach in two locations on the Ribbon, you can find this button on the Home tab in the Editing group and on the Formulas tab in the Function Library group.

When you select a cell to the right of or below a range of numeric values and then click AutoSum, Excel automatically includes that range in the formula and calculates the values.

Clicking AutoSum enters a formula that uses the SUM function to calculate the numeric values directly above or to the left of the selected cell.

For example, to quickly total the numbers for January, you just have to select cell B7 and then click AutoSum. A color marquee surrounds the cells that are selected in the formula that is entered in cell B7. After pressing ENTER, the result of the formula is displayed in the selected cell (B7), and the formula appears in the formula bar.

Page 8: Js02 Muhamad Hakimi Azali Bin Azlan

Cell B7 displays the result of the formula. The formula itself appears in the formula bar whenever that cell is selected.

In a formula that uses a function, such as SUM, the cell reference that appears inside the parentheses is the argument of the formula. The argument determines which values the formula is going calculate. The colon (:) in the cell reference (B3:B6 in the example) indicates that the cell reference is a range of cells. Parentheses are always required in a formula that uses a function — they separate the argument from the function name in the formula.

When a cell reference is used in the argument of a formula instead of the actual values, Excel can automatically update the formula result whenever the values in the referenced cells are updated.

Stop typing the same formula over and over

Once you have created a formula, you can copy it to other cells — no need to create the same formula over and over again.

For example, when you copy the formula in cell B7 to the adjacent cell C7, the formula in that cell automatically adjusts to the new location, and calculates the numeric values in column C.

Page 9: Js02 Muhamad Hakimi Azali Bin Azlan

The copied formula references and calculates the numeric values in column C.

Use a simple formula to add, subtract, multiply, or divide numeric valuesIn a simple formula, you can enter values and math operators to calculate those values. However, instead of entering values directly in the formula, you can also refer to the cells that contain the values that you want to calculate. Using cell references in a formula makes sure that any changes to the values are automatically updated in the calculation result of the formula.

1. On a worksheet, click the cell in which you want to enter the formula.2. To start the formula, type =3. To enter the first numeric value, do one of the following:

o Type the value that you want to use.

TIP   For example, type 10

o Select the cell that contains the value that you want to use.

TIP   For example, select cell A1.

4. To enter the math operator that you want to use, do one of the following:o To use a plus sign (+) to add the values in the formula, type +o To use a minus sign (-) to subtract the values in the formula, type -o To use an asterisk (*) to multiply the values in the formula, type *o To use a forward slash (/) to divide the values in the formula, type /

5. To enter the next value numeric value, do the following:

Page 10: Js02 Muhamad Hakimi Azali Bin Azlan

o Type the value that you want to use.

TIP   For example, type 5.

o Select the cell that contains the value that you want to use.

TIP   For example, select cell B1.

6. Repeat steps 4 and 5 for any additional math operations and values that you want to include in the formula.

TIP   For an operation to take precedence in the calculation, use parentheses around that operation. For example, type =(10+5)*2 or =(A1+B1)*C1.

7. When the formula is complete, press ENTER.

By default, the resulting value of the formula appears in the selected cell, and the formula itself is displayed in the formula bar.

What can I use in a formula to mimic calculator keys?

Page 11: Js02 Muhamad Hakimi Azali Bin Azlan

Use the SUM function to total numeric values in a column or rowTo calculate the total of a series of numeric values in a row or column, you do not have to enter all those values manually into a formula. Instead you can use a predefined formula that uses the SUM function.

1. On a worksheet, click a cell below or to the right of the numeric values that you want to total.

2. On the Home tab, in the Editing group, click AutoSum  .

Page 12: Js02 Muhamad Hakimi Azali Bin Azlan

TIP   AutoSum is also available on the Formulas tab, in the Function Library group.

3. Press ENTER to display the SUM function result in the selected cell.

The formula itself appears in the formula bar.

TIP   If you are looking for a quick way to total values in a column, you may want to place your data in an Excel table. In an Excel table, you can add a total row so that you can instantly summarize the values in a column. For more information, see the training course Use Excel tables to manage information.

There is no SUBTRACT function in Excel

Although there is a SUM function, there is no SUBTRACT function. Instead, use the minus (-) operator in a formula; for example, =8-3+2-4+12. Or, you can use a minus sign to convert a number to its negative value in the SUM function; for example, the formula =SUM(12,5,-3,8,-4) uses the SUM function to add 12, 5, subtract 3, add 8, and subtract 4, in that order.

Fill a formula into adjacent cellsWhen you fill a formula into adjacent cells, either in a row or column, the formula automatically adjusts to calculate the values in the corresponding row or column.

1. On a worksheet, select the cell that contains the formula that you want to fill into adjacent cells.

2. Drag the fill handle   across the cells that you want to fill.

NOTE   The fill handle is displayed by default, but if it is not available you must first specify an option in Excel to enable the fill handle.

3.To specify how you want to fill the selection, click Auto Fill Options  , and then click the option that you want

NOTE   If automatic workbook calculation is not enabled, formulas will not recalculate when you fill cells. To check your workbook calculation options, do the following:

1. Click the File tab, click Options, and then click the Formulas category.

2. Under Calculation options, look under Workbook Calculation.

o Automatic    Formulas automatically recalculate.

Page 13: Js02 Muhamad Hakimi Azali Bin Azlan

o Automatic except for data tables    Formulas automatically recalculate, unless the formula is in a data table.

o Manual    Formulas never automatically recalculate.

o Recalculate workbook before saving    This option is available only if Workbook Calculation is set toManual. If this check box is selected, formulas do not automatically recalculate until you save the workbook. Note that several other actions can cause the workbook to be saved, such as using the Send To command.

Tips

You can also fill the active cell with the formula of an adjacent cell by using the Fill command (on the Home tab in the Editing group) or by pressing CTRL+D to fill a cell below or CTRL+R to fill a cell to the right of the cell that contains the formula.

You can automatically fill a formula downward, for all adjacent cells that it applies to, by double-clicking the fill handle of the first cell that contains the formula. For example, cells A1:A15 and B1:B15 contain numeric values, and you type the formula =A1+B1 in cell C1. To copy that formula into cells C2:C15 (so that C2=A2+B2, C3=A3+B3, and so on), select cell C1 and double-click the fill handle.

If you are looking for an even faster method for filling formulas, you may want to place your data in an Excel table. In an Excel table, you can create a calculated column by simply entering one formula, and Excel automatically uses that formula in the whole column. Magic math!

3.HOW TO INSERT SYMBOL RM WITH 2 DECIMAL PLACES.Excel provides a convenient feature to deal with currency values. Like previous versions of Excel, Excel 2010 lets you easily convert values into currency values without having to manually change the data type. Using RM function you can place decimal values by your choice and round-off currency values. This post will cover ways in which you can deal with currency values and use the RM function. Excel 2010 includes a list of currency symbols  to easily pick the required currency and use its symbol with values. The default currency symbol is set to the RM, which can be easily selected from the data type pull-down menu available on the ribbon. The Format Cells (accessible from right-click context menu) allows you to change the currency symbol and and set decimal places according to your requirements.

Page 14: Js02 Muhamad Hakimi Azali Bin Azlan

Launch Excel 2010 and open a spreadsheet in which you want to convert data into Currency values. For Instance, we have included a spreadsheet containing fields; Product ID and Price as shown in the screenshot below.

1.FIRST HIGHLIGHT THE NUMBER THAT WE WANT TO CHANGE TO 2 DECIMAL PLACES
