The following basic topics are covered here.

**Fraction**: A fraction is used to mean a part of a whole. A fraction can be simplified further to get another fraction, which may be their simplest lowest form.

There are many types of fractions; for example,

- proper & improper fractions,
- mixed fractions,
- equivalent fractions,
- like and unlike fractions, etc.

**Square Root**: A number x is called a square root of another number b if we have x^{2}=b. Here, we will learn how to simplify square roots in the simplest radical form.

**How to Solve an Equation**: Depending upon the degree of an equation, we have the types of equations; for example, linear equations, quadratic equations, etc. On this page, we will learn how to simplify those equations.

- A linear equation in one variable x has the form ax+b=0, where a≠0.
- A quadratic equation in one variable x has the form ax
^{2}+bx+c=0, where a≠0.
