All functions start with a name and are followed by brackets. After that, each function is different. Some functions have nothing inside the brackets but most do. What is inside the brackets will depend on the function. So there is not a standard syntax for functions, other than having a name and brackets. In order to use them in a formula, there must be an equals sign at the very beginning of the formula. More than one function can be used inside a function, but the equals sign is only required at the beginning of the formula.
A function will have a name, brackets and inside the brackets certain values will be needed, depending on the function. Some functions, like NOW(), do not need anything inside the brackets. Most functions have a set number of values needed in the function, and many have ones that are optional.
You could say the name, the brackets and the arguments. All functions will have a name and brackets. For most functions there will be something inside the brackets, known as arguments, although some functions have no arguments. Here are the two forms.=NAME()=NAME(arguments)The TODAY function has no arguments so it can be entered like this:=TODAY()The SUM function must have arguments, so it could be something like this:=SUM(A2:A20)You could say the name, the brackets and the arguments.

The text in the brackets must be a question.
It is called the tagname. eg: <head> - here head is the tagname.
Brackets means to work out whatevers inside the brackets before you work out anything else!
Use the same rules inside brackets as you would outside of brackets. There is no difference between the two.
Parentheses are usually placed inside brackets.
Square brackets are used inside regular parentheses, in a sentence.
If it's inside the brackets it means that it belongs to that specific term, but if it was outside the brackets, it means that every term inside the brackets goes out with opossite sign. For example: [ -5x + 6y ] = -5x + 6y , the negative is only for 5x, but if you had - [ -5x + 6y] = 5x - 6y , every term inside the bracket goes out with opossite sign.
