Module 1 of 1

Numbers, percents, and basic algebra

The math test covers everyday number skills, basic algebra, and geometry. You get a formula sheet, and an on-screen calculator is available for most questions.

Tips

  • Read the whole question before you start working.
  • Write down what the question is asking for.
  • Estimate first, so you can tell if your answer makes sense.
  • For percents, remember that "percent" means "out of 100." 25% is 25/100, or 0.25.
  • To solve for x, do the same thing to both sides of the equation until x is alone.
