What math formulas are needed for the ACT?

Arithmetic mean (average) = Sum of values / Number of Terms.

  • Probability = Target outcomes / Total outcomes.
  • Quadratic Formula: x = −b ± √b²-4ac/2a.
  • Distance Formula: d=√(x₁ – x₂)² + (y₁ – y₂)²
  • Slope Formula: Slope = y₂ – y₁ / x₂ – x₁
  • Slope Intercept: y=mx+b.
  • Midpoint Formula: (x₁+x₂) / 2, (y₁+y₂) / 2.

    • Does the ACT have math formulas?

    The two biggest challenges of ACT Math are the time crunch—the math test has 60 questions in 60 minutes! —and the fact that the test doesn’t provide you with any formulas. All the formulas and math knowledge for the ACT comes from what you’ve learned and memorized.
