Before we solve multiple-choice questions on Algebra, lets first learn what is an Algebra?

The branch of mathematics where we study numbers is called Arithmetic. The branch of mathematics where we study shapes is called geometry and the branch of mathematics where we study the letters and other general symbols are called Algebra.

Algebras can be used to represent numbers and quantities in formulae and equations.

The use of letters helps us in numerous ways

- We can write rules and formulae by using letters.
- We can discuss any number and not only a specific number.
- Unknown quantities can be represented by letters.
- As we can represent letters for numbers, numerous operations can be performed on letters as on numbers.

By learning the methods for determining the unknown values we can develop powerful tools for solving puzzles and many day-to-day life problems.
