What is the content covered in the Pre-Algebra and Algebra section?

• A. Special notation for multiplication and division with variables, algebra word problems, order of operations, and simplifying expressions.
• B. Geometry shapes and the Pythagorean theorem.
• C. Basic arithmetic with whole numbers.
• D. Set theory and logic.

Answer: (A)

Algebra centers on using letters to stand in for numbers and applying consistent rules to manipulate those expressions and solve equations. In the Pre‑Algebra and Algebra section you learn how to read and work with multiplication and division when variables are involved (such as 3x or x/4), how to translate word problems into algebraic expressions and equations, and how to apply the order of operations to evaluate expressions correctly. You also practice simplifying expressions by combining like terms and using basic properties, and you learn when factoring can be useful. This set of topics is distinct from geometry, which covers shapes and the Pythagorean theorem; from basic arithmetic with whole numbers, which focuses on straightforward computations without variables; and from set theory and logic, which belong to other areas of math.
