Commas

Abstract

Semicolons Semicolons are used to link two very closely related sentences or to separate items in a series that already have commas. Using a semicolon means you should not use a conjunction (such as “and”). The Mariners used to be a great team; this season they finished in last place. This course will review past material; introduce fractions, decimals, and exponents; test your ability to apply basic mathematics to real world problems; and train you to think like a mathematician.
