Arithmetic is the oldest and most widely used branch of mathematics in the history of the world. In its most basic form, arithmetic encompasses addition, subtraction, multiplication, and division. Arithmetic is used in our everyday lives, from completing simple tasks such as counting to performing complex feats such as computing business models.

Therefore, if you want to achieve a good quantitative score, a solid foundation in numbers and the arithmetic operations that govern them is absolutely essential.
