What are the basic formulas of maths?
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.
