They can be interchanged with parentheses or square brackets. However, if there are three levels of grouping in a nested expression, parentheses () are generally used in the inner most groupings. Square brackets [] are used in the next higher level grouping.Braces {} are used in the most outer groupings.These three types of brackets are commonly used together in a nested expression as follows: { [ ( ) ] }An example of a nested mathematical expression is:{[a(b + c) + d]/e}(2) When braces {} are used to identify a set of elements, they are used to enclose all the elements of the set.For example:. . Set "A" consists of the following elements: a,b,c,d,e. A = {a, b, c, d, e} Thanks for writing.Staff www.solving-math-problems.com
