# Parent Letter Unit 2: Expressions & Equations

Dear Parents,

Below is information regarding Unit 2: Expressions & Equations. Look for additional information for future units.

# Expressions & Equations

By the end of this unit, students will understand that:

• Variables can be used to represent numbers in any type mathematical problem.
• Understand the difference between an expression, an equation, and an inequality.
• Expressions are simplified and equations are solved for the variable’s value.
• Write and solve multi-step equations including all rational numbers.
• Expressions, equations, and inequalities can be used to represent and solve real world problems

# Vocabulary

• Algebraic Expression: an expression consisting of at least one variable and also consists of numbers and operations
• Numerical Expression: an expression consisting of numbers and operations
• Coefficient: the number part of a term that includes a variable. For example, 3 is the coefficient of the term 3x
• Constant: a quantity having a fixed value that does not change or vary, such as a number. For example, 5 is the constant of x + 5
• Equation: a mathematical sentence formed by setting two expressions equal
• Inequality: a mathematical sentence formed by placing inequality symbols ( >,<,≥,or ≤) between two expressions.
• Term: a number, a variable, or a product and a number and variable.
