Key Concepts

Rational Numbers

Rational numbers are numbers that can be expressed as a fraction of two integers, where the denominator is not zero. They encompass numbers in the form a/b and include integers, as every integer can be written as that integer over 1.

Addition of Rational Numbers

To add rational numbers, especially fractions, it is important to have a common denominator. When the fractions share the same denominator, you simply add the numerators while keeping the denominator constant, and then simplify the resulting fraction if possible.

Negative Numbers

Negative numbers represent values less than zero and are indicated by a sign preceding the number. In arithmetic operations, such as addition, handling negative numbers requires attention to their signs, as adding two negative numbers results in a sum with a larger negative magnitude.
