Introductory Algebra - What's New

Enhancements

  • Over 80 new question types have been added. The new question types provide a greater correlation with the exercises in the textbook.

  • Some existing question types were split into separate questions in order to allow instructors greater control of the content that their students will see.

New Questions

R.2 Review of Prime Numbers, Factoring, and LCM
  • Added six question types where the number of input boxes remains constant from question type to question type.
1.2 Addition with Integers
  • Added one question type involving vertical addition.
2.5 Order of Operations with Negative Numbers and Fractions
  • Added one question type involving fractions and the order of operations.
3.1d Applications of Linear Equations: Multiplication and Division
  • Improved one question type so that the base of the triangle is indicated by b rather than x in order to match the formula for the area of a triangle.
3.3 More Linear Equations: ax+b=cx+d
  • Added two question types that involve the use of the distributive property.
3.5b Working with Formulas
  • Added two question types that provide a formula and ask the student to solve for a particular variable.
4.2 Graphing Linear Equations by Plotting Points
  • Split three question types into six for better control over integer and fractional answers.
4.3 The Slope-Intercept Form y=mx+b
  • Added two question types where the student is given the graph of a line and they must determine the slope, y-intercept, and equation of the line.
4.4 Finding the Equation of a Line
  • Split five question types into ten for better control over questions involving parallel and perpendicular lines.
  • Added two question types where the student is given the equation of a line and must determine the equation of the line in slope-intercept form that is either parallel to or perpendicular to the given line and another point.
  • Added one question type where the student is given an equation of a line in standard form and must determine the slope of a line parallel to and perpendicular to the given line.
5.4 Applications: Distance-Rate-Time, Number Question types, Amounts and Costs
  • Added five word question types.
5.5 Applications: Interest and Mixture
  • Added two word question types
6.3b Evaluating Polynomials
  • Added two question types that require the student to evaluate a function at a value other than a real number. For example, “Given g(x) find g(a+3)."
7.5 Solving Quadratic Equations by Factoring
  • Added three question types where the student must solve a factored equation.
8.1a Defining Rational Expressions
  • Added two question types that ask to state any restrictions on the given expression where “No Restrictions” is the answer to both question types.
8.4 Complex Algebraic Fractions
  • Added two question types to simplify a given expression involving multiple operations.
8.5 Solving Equations Involving Rational Expressions
  • Added three question types where the student must state any restrictions and then solve
9.1 Evaluating Radicals
  • Added four question types where the student must determine if the given radical is rational, irrational, or nonreal.
9.3a Addition and Subtraction of Radicals
  • Split two question types into five for better control over the types of question types students receive.
9.4b Division of Radicals
  • Added eight question types involving rationalizing binomial denominators.
9.6 Rational Exponents
  • Split one question type into two in order to separate question types with and without a negative sign.
  • Added three question types where the student must simplify algebraic expressions with rational exponents
10.1 Quadratic Equations: The Square Root Method
  • Split one question type into three question types where the answer reduces, reduces partially, or does not reduce.
10.3 Quadratic Equations: The Quadratic Formula
  • Added twelve question types and adjusted the answer entry format based on instructor feedback.
