- Arithmetic (from Ancient Greek ἀριθμός (arithmós) ’number’, and τική [τέχνη] (tikḗ [tékhnē]) ‘art, craft’) is an elementary part of mathematics that consists of the study of the properties of the traditional operations on numbers—addition, subtraction, multiplication, division, exponentiation, and extraction of roots. In the 19th century, Italian mathematician Giuseppe Peano formalized arithmetic with his Peano axioms, which are highly important to the field of mathematical logic today.
- Algebra (Wikipedia)
Algebra is the branch of mathematics that studies algebraic structures and the manipulation of statements within those structures. It is a generalization of arithmetic that introduces variables and algebraic operations other than the standard arithmetic operations such as addition and multiplication.
- Zhuangzi (book) (Wikipedia)
The Zhuangzi (Chinese: 莊子, historically romanized Chuang Tzŭ) is an ancient Chinese text from the late Warring States period (476–221 BC) containing stories and anecdotes that exemplify the carefree nature of the ideal Taoist sage. Named for its traditional author, “Master Zhuang” (Zhuangzi), the Zhuangzi is one of the two foundational texts of Taoism, along with the Tao Te Ching.
