When terms have the same algebraic factors, they are like terms. When terms have different algebraic factors, they are unlike terms. Here we will learn how to write expressions and how to add expressions. While adding and subtracting expressions, first look for like terms and add them; then handle unlike terms. Let's understand this better!
