In our study of algebra, we will encounter a wide variety of algebraic expressions. Typically, expressions use the two most common variables, x and y. However, expressions may use any letter (or symbol) for a variable, even Greek letters, such as alpha (\alpha) and beta (\beta).
Algebraic expression, or variable expression, is a mathematical expression consisting of two main parts, variables and constants, joined together using mathematical operators addition, subtraction, multiplication, division, and exponentiation. Here are a few examples of algebraic expressions: 2x + 9. 5x + 7y + 3z – 11. 5 x 2 + 4 y − 3. Parts.
Use the following examples and interactive exercises to learn about Writing Algebraic Expressions. Problem: Ms. Jensen likes to divide her class into groups of 2. Use mathematical symbols to represent all the students in her class.
Introduce algebraic expressions by connecting them to hands-on manipulatives (such as algebra tiles) or real-life situations, so students can begin to attach meaning to the symbols and their mathematical operations. Vocabulary is key for students to understand how to read and write algebraic expressions.
