You cannot really classify formulas, as there are an infinite amount of them and they can contain many types of elements. You can classify functions.
=MAX(A1:A100100) is a formula that uses a statistical function.
In Excel an equation can be a formula. All formulas in Excel must start with the equals sign. That is what tells Excel it is a formula.
All formulas must begin with the equals sign. That is how Excel knows it is a formula.
83 + 2 = 85 (Excel formula: =83+2)
Excel assumes data is text initially, but can treat it differently depending on the way you enter it. That is why you enter an equals sign at the beginning of a formula to indicate to Excel that you are creating a formula.
Then it will not be treated as a formula. It will appear literally as you type it. Because cell references and functions begin with letters Excel needs the equals sign to tell it that what is following is a formula and not just a piece of text. You can actually also start a formula with a plus sign or minus sign, but an equals sign will automatically be added.
85
Functions have a name followed by brackets. So when you have a name followed immediately by brackets, it is a function. On the worksheet it would also have an equals in front of it. In a module it would have the keyword Function in front of it.
If the first character of a cell is an equals sign (=), then the cell contains a formula.
In an Excel spreadsheet and equals sign normally starts a formula. You can also start with a plus or minus or start a function with the @ symbol, because some spreadsheet applications use that, but they will be converted to an equals sign. The equals signs tells Excel that you are going to use a formula, so if you started a function without it, the function would be treated like a piece of text.In an Excel spreadsheet and equals sign normally starts a formula.
