You start with the equals sign. After that there is no fixed rule, as formulas are completely different to each other. If you are using functions then there are some rules. First there is the name of the function. After that you have an opening round bracket. Most functions will have arguments in them, and some will not. The square brackets used below indicate that there may or may not be arguments, but are not part of the function. If there are any arguments, they need to be put inside the round brackets. Finally there will be the closing round bracket.
=function_name([arguments])
This is how the SUM function can work:
=SUM(A2:A20)
You can also have formulas with no functions. They would include values and cell references:
=20+C5-34*4
Syntax is very important when writing Excel formulas. Each formula and function will help guide you through how to format the equation. Probably the most important thing to remember about syntax is to begin all formulas with the equal sign, or Excel will just interpret your entry as text and not calculate anything.EXAMPLE: =SUM(A1:A12) [Adds the contents of cells A1 through A2]
Excel does not convert formulas from anything. Formulas are displayed as you enter them in cells. [[What do excel convert all formulas from#ixzz15yaIeMD4|]]

lower to upper
All formulas are converted to upper case when they have been typed in.
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.
Rules can be made in Conditional Formatting. Some kinds of formulas could be said to have rules. All functions have a syntax, which are the rules that determine how they have to be used. The IF function can be used to define rules to get a calculation to happen.
recalculates all formulas
uppercase to lowercase and/or absolute to constant
Well, formulas in general don't always start with a sign, but it might be talking about Excel, where they always start with an equal sign (=).
All formulas must begin with the equals sign. That is how Excel knows it is a formula.
All formulas recalculate when Excel opens, so if a database in Excel has formulas in it, it will be recalibrated. It could also be linked to another file or external source which may make it change when it is opened.
