Pre-Algebra / Elementary Algebra

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

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.
