Unit Outline

In this chapter, you’ll learn how mathematical expressions can be represented and evaluated to solve various problems. Mathematical expressions use symbols, numbers, and operations to represent quantities and relationships. You’ll explore how to write expressions using variables to represent unknown values and constants for known values. By following the order of operations, you’ll learn to evaluate these expressions step by step, ensuring accurate results. You’ll also practice simplifying expressions by combining like terms and using properties of operations such as the distributive property. Understanding how to represent and evaluate mathematical expressions will help you solve real-world problems, make calculations more efficiently, and develop a solid foundation for more advanced mathematical concepts.
