- The natural numbers are the numbers 1, 2, 3, 4, ….
- The integers are the numbers …, -3, -2, -1, 0, 1, 2, 3, ….
- The rational numbers are numbers that can be expressed as a fraction of two integers, a/b, where b is not equal to 0.
- The irrational numbers are numbers that cannot be expressed as a fraction of two integers.

**Chapter 2: Polynomials**

- A polynomial is a mathematical expression of the form ax^n + bx^(n-1) + cx^(n-2) + … + d, where n is a non-negative integer and a, b, c, …, d are real numbers.
- The degree of a polynomial is the highest power of x that appears in the polynomial.
- The leading coefficient of a polynomial is the coefficient of the term with the highest power of x.
- The roots of a polynomial are the values of x that make the polynomial equal to 0.

**Chapter 3: Quadratic Equations**

- A quadratic equation is an equation of the form ax^2 + bx + c = 0, where a, b, and c are real numbers.
- The quadratic formula is a formula that can be used to solve any quadratic equation. The formula is:

- The discriminant of a quadratic equation is b^2 – 4ac. The discriminant tells us whether the quadratic equation has two real roots, one real root, or no real roots.

**Chapter 4: Triangles**

- A triangle is a polygon with three sides and three vertices.
- The sum of the interior angles of a triangle is always 180 degrees.
- The area of a triangle can be calculated using the formula:

```
A = 1/2bh
```

where b is the base of the triangle and h is the height of the triangle.

**Chapter 5: Circles**

- A circle is a shape with all points equidistant from a center point.
- The radius of a circle is the distance from the center of the circle to any point on the circle.
- The diameter of a circle is twice the radius of the circle.
- The circumference of a circle is the distance around the circle. The circumference of a circle can be calculated using the formula:

- A statistic is a characteristic of a sample.

**Chapter 7: Probability**

- Probability is the study of chance or likelihood.
- An event is something that can happen or not happen.
- The probability of an event is a number between 0 and 1, where 0 means the event is impossible and 1 means the event is certain.
- The sum of the probabilities of all possible events is always 1.
