π Math Study Notes
Not memorization β understand the why and the formula follows naturally
π« Elementary & Middle School Math
Build a strong foundation with number sense, operations, fractions, and decimals.
Arithmetic
Place value, addition, subtraction, multiplication, division, PEMDAS, factors, and multiples
Arithmetic = the foundation of all math β patterns behind the four operationsFractions, Decimals & Percents
Simplifying fractions, operations, conversions, ratios, proportions, and percent problems
Dividing fractions = multiply by the reciprocal β why flip?π High School Math
Algebra, geometry, and beyond β covering standard high school and AP-level content.
Algebra
Linear equations, inequalities, systems of equations, quadratic equations, and polynomials
Algebra = balance scale β same operation on both sides keeps it equalGeometry
Angles, triangles, Pythagorean theorem, circles, 3D shapes, and coordinate geometry
Triangle angles sum to 180 degrees β proved by sliding angles to a lineStatistics & Probability
Descriptive statistics, probability rules, distributions, and AP Statistics prep
Mean vs median β one billionaire changes the mean, not the medianCalculus
Limits, derivatives, integration, and applications β AP Calculus AB/BC level
Derivative = instantaneous rate of change β slope of a curveHow to Use These Study Guides
- Read the concept explanations β don't skip straight to examples
- Work through every example on paper, step by step
- Attempt the practice problems before checking answers
- Review your mistakes β understanding errors is the fastest path to improvement
- Math builds on itself: review prerequisite topics if you feel shaky on fundamentals
