Mathematics Explanation: Chapter 1 (Rational Numbers)

Definition of Rational Numbers: Numbers that can be expressed in the form p/q, where p and q are integers and q ≠ 0.
Why are Rational Numbers Needed?
- Some equations, like x + 5 = 5, can be solved using whole numbers.
- Some equations, like x + 18 = 5, require negative numbers, leading to the introduction of integers.
- However, equations like 2x = 3 require numbers like 3/2, which are neither whole numbers nor integers, introducing rational numbers.
