The HLOOKUP function searches for value in the top row of table_array and returns the value in the same column based on the index_number. It has nothing to do with multiplying or adding cells, unless you use the results in some kind of calculation. If this does not answer your question, please ask a more specific question. If you want to know about both multiply and add, ask two questions--one for each subject.
There is no specific name for a multiplication formula. To do multiplication in Excel you use the star character. You can click on the cell you want the formula in, and then you can type it like: =F3*C5 This will multiply the amount in F3 by the amount in C5. You can use a cell and a value, like this: =A2*4 or =16*J33 There is also a function called PRODUCT. In it you list the cells or values you want to multiply. Using the above examples you could use it like this: =PRODUCT(F3,C5) =PRODUCT(A2,4) =PRODUCT(16,J33)
It is a formula that the user creates themselves, instead of using the built-in functions.

You can click on it in the Formula Bar near the top of screen, or you can press the F2 key.
It is a function
It is used to copy the formula down or across.
There is no single formula that can be said to be the best. Every calculation you do is different and there are different ways in Excel to do the same calculation. It will depend on the calculation you want. So the question cannot really be answered. Generally you can use the plus(+), minus(-), multiply(*) and divide(/) operators in Excel and they would be used in basic mathematical calculations. Functions like SUM can also be used to do some basic calculations.
Not entirely, but you can use a mouse to select ranges you include in a formula.
You would first need to know how the fat in milk is calculated and have a formula for it. You would need to know what values are needed to do it. Then you would need to get the values you need and enter them into cells in the spreadsheet. Using these cell references to build your formula, you could do the calculation.
In Excel it allows you to enter formulas using the mouse, by clicking on cells as you type a formula, instead on typing the cell references.
Under the formulas tab, there is an option called "Show Formulas" in Formula Auditing. This applies for Excel 2010 (what I am using) and should apply for Excel 2003 and 2007 as well. For older options (or if there is no such option in Excel 2003/2007, search for something similar).
No, not with a formula. What you can do is use the Filter facility to hide records, which are always in rows. Using an Advanced Filter, you can extract data from an overall set.
