No, not always.
When writing a range of numbers, square brackets are used to indicate the end number is included and round brackets are used to indicate the end number is excluded.examples:[1, 4] = all numbers ≥ 1 and ≤ 4(1, 4] = all numbers > 1 and ≤ 4[1, 4) = all numbers ≥ 1 and < 4(1, 4) = all numbers > 1 and < 4
There are no following numbers!
BODMAS. Brackets, Order, Division, Multiplication, Addition & Subtraction.If the problem has numbers in brackets - solve those first (following the rules for the symbols in the bracketed part). Then numbers raised to a power (ordered) come next, followed by division, multiplication, addition and finally subtraction.For example... to solve (2x62)-3/4...The sum inside the brackets come first... 62 = 36 times that by the 2 = 72The sum 3/4 equals 0.75, and you subtract that from the 72 obtained in the first sum.. to give the answer 71.25
The ancient Romans had no real reasons for such large numbers but if necessary their system of numeracy was and still is capable of such huge numbers by a system of brackets and superscripts as the following shows:- (MMM)(M) which means 1,000*3,000*1,000*1,000 = 3,000,000,000,000 or as 3.0*1012 in scientific notation

There are both "square" and "curly" brackets used in algebra. They are [] and {} respectively in type. Usually square brackets are used to group smaller numbers of terms than curly brackets, and even square brackets are used only to group quantities some of which are in parentheses. Thus a suitable use example would be {[(a - b)(c + d) - a2]/[(fg + hj)/[k(l/m)]}. Larger square brackets are also used to set off numbers in matrix format.
Brackets are used in different ways in a spreadsheet. Most commonly you will see them in functions, with what is needed for the function, referred to as arguments, being put inside the brackets. All functions have brackets and most require that something is put inside them. Examples include the following:=SUM(A1:A15)=Left(A2,5)Brackets can be used in calculations to change the precedence of operators. This is standard from the laws of mathematics. For example, in mathematics you do all multiplications and divisions before any additions and divisions. The following calculation gives 20, not 60, because the multiplication has to be done first:=10+2*5To get the 10+2 done first, which will make the final result 60, you would include it in brackets, like this:=(10+2)*5Brackets are sometimes used to indicate negative numbers, instead of using the minus sign. The proper name for these kind of brackets or round brackets is parentheses. You will also see the curly brackets { and } which are properly called braces. They are used to indicate arrays, which are lists of values that can be used in formulas.

It stands for "first, outsides, insides, last". It is how to multiply out double brackets such as (x+3)(x-4). First numbers, inside numbers, outside numbers, last numbers.
The rule method is used to describe any set of numbers, so put any sequence of numbers in brackets and there you go.
