Parentheses
You use the distributive property. That is, you look for a common factor, divide each of the terms within parentheses, brackets, or whatever by this common factor, and write the common factor once outside the parentheses. For example: 10x + 15y Here you have a common factor of 5, so you can take this factor out: 10x + 15y = (10x + 15y) = 5(2x + 3y)
8- (2x3x9)
It depends what subject you use it for. For example, if you use parentheses in terms of language arts then, it would be the same thing no matter how you use it. In that case, it means you want to add extra information that isn't necessarily essential to the meaning. It can also be the definition of a term. If you use parentheses in math, then it can mean to multiply. It can also mean to work what is inside the parentheses first.
2 3 3 5 and 11 are the Prime Factors (excluding 1 and 990) All other factors of 990 may be generated by grouping these prime factors as in: (2 x 3) = 6 (2 x 3 x 3) = 18 (3 x 3) = 9 (3 x 5) = 15 (2 x 3 x 3 x 5) = 90 (3 x 11) =33 And so on . . .

Parentheses
There are a couple types of grouping symbols used in math. These are mainly parentheses and brackets. Both plain and curly brackets are used in some equations.
Brackets or parentheses.
Parentheses ( ), brackets [ ], and braces { }
they are both grouping symbols in math
Grouping symbols are parentheses such as {}, (), []. They need to be evaluated before other operations. If there are a number of nested parentheses, they must be evaluated starting with the innermost.
Th answer is grouping symbols : )
Grouping symbols are symbols such as parentheses or brackets, that indicate that the operations within them should be done first. When an expression contains more than one pair of grouping symbols, the computations in the innermost grouping should be done first.
Parentheses in formulas are used to establish the order of operations. They help clarify which operations should be performed first and ensure that the formula is evaluated correctly. Without parentheses, the formula could produce a different result than intended.
Parentheses and brackets are what are known as grouping symbol. They keep two or more quantities separate from the rest of the problem. For example, n-2 180. Without parentheses the problem is wrong. But add in parentheses and the problem looks like this (n-2) times 180.
