It is common to group factors in pairs with parentheses surrounding each pair.
Parentheses
To use the distributive property to remove the parentheses in the expression ( (y + 5) \cdot 10 ), you multiply each term inside the parentheses by 10. This gives you ( y \cdot 10 + 5 \cdot 10 ), which simplifies to ( 10y + 50 ). Thus, the expression without parentheses is ( 10y + 50 ).

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)
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.

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.
An integer is often placed in parentheses to denote that it is part of a specific grouping or to indicate a particular operation, especially in mathematical expressions. Parentheses can clarify the order of operations or isolate the integer for emphasis, such as in coordinate pairs or function notation. Additionally, they can be used to indicate that the integer is being treated as a single entity in calculations or expressions.
In the GEMDAS rule, "G" stands for "Grouping." This refers to the use of parentheses or brackets in mathematical expressions to indicate which operations should be performed first. Grouping ensures that calculations within the parentheses are prioritized over other operations, helping to clarify the order of operations in complex equations.
