Brackets can be used to add additional information to a sentence. The number on the left denotes the least element or lower bound. Image transcription text. I'll make a brief note of online math tutorials. Closed intervals on number lines are denoted using filled-in circles at the endpoints; open intervals use circles that are not filled in for the endpoints: To express the same intervals above using inequalities: - union represents the joining together of two sets, - intersection represents the overlap between two sets. Parentheses are always used in pairs; you must have both an opening and a closing parenthesis. Here, represents the adjoint.
