### what is the "&" symbol for in excel 2010?

The "&" symbol is commonly known as "ampersand" and it is a calculation operator. Ampersand can be used in Excel 2010 to join text items from different cells. It functions much similar as "CONCATENATE" function. The output value you will get by using ampersand function will be the same as the one you will get by using CONCATENATE function. For example, =A1 & B1 returns the same value as=CONCATENATE(A1, B1)

To know more about the CONCATENATE/ ampersand function, you can refer to the following webpages:

### what are the formulas in grading the grades uisng microsoft excel

Formulas are used to specify calculations based on values in designated cells. Excel supports basic calculations as well as statistical, trigonometric and other specialized functions.

Formulas used in Excel must follow a certain syntax.

1. All formulas begin with an equals sign (=).
2. Some formulas use operands such as +,-, *,/ for addition, subtraction, multiplication or division.
For example, the formula =A1+A2+A3 would add the contents of cells A1, A2 and A3.
3. Other formulas refer to different functions such as SUM, AVERAGE and others.
For example, the formula =SUM(A1:A3) would add the contents for the range A1 through A3.
4. Formulas can be combined with operands.
For example, the formula =10*SUM(A1:A3) would add the contents cells A1 through A3 and multiply them by 10.
5. Functions can be nested within each other.
For example, the formula =SQRT(10*SUM(A1:A3)) would take the square root of ten times the sum of cells A1 through A3. When functions are nested, it is important that the number of left parentheses match the number of right parentheses.

### what is the function of Microsoft excel?

Ok - if your question is "What is Excel" - then the answer is that it is a spreadsheet program that allows you the ability to compute data (usually numbers) for example, pulling together a list of hours worked by employees and adding them up automatically. It also can be used to develop sophisticated computational models and I have used it to develop professional services proposal sizing tools using formulas and functions ... which is a good segwey into my other answer.

If your question is "what is a function or formula in Excel" - then the answer is a function or formula in Excel is a collection of mathematical, text, statistical, etc. preprogrammed tools that allows you to manipulate the data you have in your spreadsheet e.g. a SUM() function that adds a series of numbers, and AVERAGE() funtion that computes the average of a series of numbers, etc.

Hope that helps!
