## Study Notes

## Maths

Maths is a branch of science that uses numbers, symbols, and concepts to understand and describe the world around us. It is a fundamental subject that is used in various fields, including science, engineering, and business. There are two main branches of maths: algebra and geometry.

### Algebra

Algebra is a branch of mathematics that deals with mathematical symbols and the rules for manipulating these symbols, including numbers and operations on numbers. It involves solving equations and understanding the relationships between different variables. Algebra is used in various fields, such as finance, statistics, physics, and computer science.

#### Equations

An equation is a mathematical statement that asserts the equality of two expressions, which involve values, known as variables. Some common equations include:

- Linear equations: These equations involve only first-degree powers of the variables.
- Quadratic equations: These equations involve squared terms of the variables.
- Exponential equations: These equations involve exponential functions, such as 2^x.

#### Functions

A function is a rule that assigns an output value to every input value. Functions are used to model real-world situations, such as the relationship between the distance a ball travels and the force applied to it.

### Geometry

Geometry is a branch of mathematics that deals with the properties and measurements of points, lines, angles, surfaces, and solids. The word "geometry" is derived from the Greek words for "earth" and "measurement". Geometry is used in various fields, such as architecture, engineering, and design.

#### Points and Lines

A point is a location in space, while a line is a set of points that extend infinitely in two directions. Lines can be straight or curved, and they can intersect other lines at various angles.

#### Shapes and Areas

Shapes are two-dimensional figures that have length and width but no thickness, while areas are the amount of space inside a shape. Some common shapes include circles, triangles, and squares, and their areas can be calculated using formulas.

#### Volume and Solids

Volume is the amount of space inside a three-dimensional figure, while solids are three-dimensional figures that have length, width, and height. The volume of solids can be calculated using formulas, such as the volume of a sphere or a cylinder.

In conclusion, maths is a vast and diverse field that covers various topics, including algebra and geometry. Algebra deals with symbols and rules for manipulating these symbols, while geometry focuses on the properties and measurements of points, lines, shapes, and solids. Both branches of maths are essential for understanding and describing the world around us and are used in various fields, such as science, engineering, and business.
