    • 1.1: Place Value
    • 1.2: Rounding Numbers
    • 1.3: Negative Numbers
      This page offers a comprehensive overview of operations with negative numbers, covering absolute value, addition, subtraction, multiplication, division, and order of operations. It explains how to evaluate expressions, detailing properties of absolute values and rules for signed numbers, alongside practical exercises, including temperature and financial examples. The text concludes by highlighting the undefined nature of division by zero.
    • 1.4: Decimals
      This page offers a comprehensive overview of decimal notation and operations, including addition, subtraction, multiplication, and division. It details the alignment of decimal points, methods for multiplying without alignment, and steps for dividing decimals. Rounding to specified place values is also covered, and exercises with answers are provided to reinforce learning.
    • 1.5: Fractions
      This page offers a comprehensive guide on fractions, covering definitions, operations (addition, subtraction, multiplication, division), simplification, and conversions between mixed and improper fractions. It includes exercises with solutions to reinforce the concepts and also explains writing fractions as decimals. Additionally, it discusses the addition and subtraction of mixed numbers, highlighting carrying or borrowing, along with calculations involving mixed numbers.
    • 1.6: Order of Operations
      This page explains evaluating mathematical expressions using the order of operations (PEMDAS), providing exercises to demonstrate how order affects results. It covers exponents and the role of grouping symbols in calculations. Additionally, it includes temperature conversion examples between Celsius and Fahrenheit, promoting practice and comprehension of these concepts.
    • 1.7: Evaluating Algebraic Expressions and Formulas
      In this section we will evaluate algebraic expressions for given values of the variables contained in the expressions.
