How does an algebra learner know what to put in parentheses when writing an algebraic expression? This video, which models how to use parentheses, begins by directing viewers to find the comma in the written algebraic phrase. The comma tells learners that everything before it is a separate expression and is to be done first. In the order of operations, parentheses always come first. The activity is part of a video series on how to write, read, and evaluate expressions.
