Note: the quotation marks in the examples are used to emphasize text and do not belong to the content of the formulas and commands.
When typing example formulas into the Commands window, note that spaces are often required for correct structure.
Braces "{}" are used to group expressions together to form one new expression. For example, "sqrt {x * y}" is the square root of the entire product x*y, while "sqrt x * y" is the square root of x multiplied by y. Braces do not require an extra space.
-Set brackets were previously inserted in the Selection window or directly in the Command window as "left lbrace <?> right rbrace". Now, a left and a right set bracket can also be inserted using "lbrace" and "rbrace", without or without wildcards.

There are a total of eight (8) different types of brackets available. The "ceil" and "floor" brackets are often used for rounding up or down the argument to the next integer: "lceil -3.7 rceil = -3" or "lfloor -3.7 rfloor = -4".
Operator brackets, also known as Bra-kets (angle brackets with a vertical line in between), are common in Physics notation: "langle a mline b rangle" or "langle a mline b mline c over d mline e rangle." The height and positioning of the vertical lines always corresponds exactly to the enclosing brackets.
All brackets may only be used in pairs. The brackets have some common characteristics:
