Braces are braces. There is no difference. The difference between braces and parentheses is that:

First, the roles are different

1, braces: this symbol indicates that the purpose is expressed in a large range through instructions and formulas.

2. Brackets: The function of brackets in primary school mathematics is to specify the operation order.

Second, the operating rules are different.

1, braces: the operation rule is brackets first, then braces.

2. Parentheses: the order of operation is first in parentheses, then outside parentheses. If necessary, calculate 2×(2+4).

Third, the characteristics are different.

1, braces: mathematically, they can be symbols of a set, such as: a = {x | x >；; 1}; In mathematics, when there is only one number in braces, it can represent the decimal part of the number. For example, {5. 1} means 0. 1.

2. Brackets: If there are brackets, count them first. Like the same level of operation, proceed from left to right in turn.
