Algebra

• Variables are symbols like x and y that stand for unknown values.
• Expressions combine both variables and constants (e.g., 2x + 3).
• Equations represent equality and require solving (e.g., 2x + 3 = 7).
• Functions define the relationship between an input and its corresponding output (e.g., f(x) = 2x + 1).

Geometry

• Basic shapes studied include circles, triangles, rectangles, and various polygons.
• Key properties involve Area, Perimeter, Volume, and Angles.
• Theorems such as the Pythagorean theorem assist in solving problems related to right triangles and the properties of similar and congruent shapes.
