numbers: =A1+A2 text: =A1&A2 or =A1&" "&A2
You can concatenate text either using the CONCATENATE function or the & operator. If you had text in cell A2 and cell B2 that you wanted to add together in another cell you could do it in either of these ways: =A2 & B2 =CONCATENATE(A2,B2)
You use the LEN function. Say you had some text in cell A2 and you wanted to find out how long it was, then you would type the following formula: =LEN(A2)
Use the CONCATENATE function to bring them together. If they were in the cells A2, A3, A4 and A5, you could bring them together like this: =CONCATENATE(A2, A3, A4, A5) You can also use the TEXT function if you want to do them separately. It uses formats from the Number formatting, but displays the numbers as text. To convert the cell contents from A2 into a 3 digit format, you could do this: =TEXT( A2, "000" )
The Average function. For example, to get the mean of the cells from A2 to A15, you would use it this way: =AVERAGE(A2:A15)
If you mean a2 x a2... the answer is a4
The mean of the numbers a1, a2, ..., an is equal to (a1 + a2 + ..., + an)/n. This number is used mostly as the average. It is called the arithmetic mean.
The a2 symbol is Italian for "a due", meaning both instruments play in unison
(a1+a2+....+am )2
If you have a cell the currently holds the text "friends," and you want it to combine a foumula and text in the same cell, here's an example: In cell A1 enter 23 (the number of friends you have). In cell A2 enter the following formula: ="You have " & A1 "friends." [You have 23 friends.] When you change the number in A1, you will see the number change in A2.
If you mean a2+b2 = c2 then it's Pythagoras' theorem
A2 width means a double narrow. A is a regular narrow A2 is double narrow and A3 is triple narrow. These are also just referred to as A, double A or triple A.
