  • Using the four basic arithmetic operations (add, subtract, multiply divide) using the order of operations (PEMDAS)
  • Finding factors and multiples
  • Identifying prime numbers
  • Performing operations with exponents and radicals
  • Performing operations on fractions
  • Converting between fractions, decimals, and percents
  • Calculating percents (including percent change)

Algebra

  • Factoring and distributing algebraic expressions
  • Performing operations on polynomials
  • Solving equations with one variable
  • Solving systems of equations
  • Solving quadratic equations
  • Solving inequalities
  • Solving for absolute value
  • Solving problems involving rates, ratios, and proportions
  • Evaluating functions

Geometry

  • Calculating angle measures
  • Classifying polygons
  • Finding perimeter and area of two-dimensional figures
  • Finding volume and surface area of three-dimensional figures
  • Converting between units of measurement
  • Using coordinate geometry to plot points, lines, and shapes; find slopes; write the equation of a line

Data Analysis

  • Reading and interpreting data on graphs, charts, and tables
  • Performing basic statistical calculations on a data set (mean, median, mode, range)
  • Finding simple and compound probability
