Greek and Roman numerals adapted and refined earlier number systems, with the Greeks using a modified base-10 system () and the Romans using a combination of letters and symbols (I, V, X, L, C, D, M)
Emergence of arithmetic and algebra
Basic arithmetic operations (addition, subtraction, multiplication, division) developed to solve practical problems (distributing goods, calculating areas)
Egyptians and Babylonians used tables and algorithms to perform complex calculations (multiplication, division, square roots)
Algebraic concepts (solving linear equations, quadratic equations) emerged in response to more advanced mathematical problems (land surveying, tax collection)
Greek mathematical traditions
Greek mathematics built upon the knowledge of earlier civilizations but placed a greater emphasis on abstract thinking and deductive reasoning
Greek mathematicians sought to understand the underlying principles and relationships between mathematical concepts
The development of axiomatic systems and mathematical proofs distinguished Greek mathematics from the more practical approaches of earlier cultures
Pythagoras and his followers
Pythagoras (c. 570-495 BCE) founded a philosophical school that combined mathematical study with mystical and religious beliefs
Pythagoreans believed that numbers and their relationships held the key to understanding the universe
(a2+b2=c2) for right triangles was a major discovery, with far-reaching applications in geometry and
Euclidean geometry
(c. 300 BCE) compiled and systematized earlier geometric knowledge in his influential work ""
Euclidean geometry is based on a set of axioms and postulates from which all other geometric propositions can be logically derived
Euclid's five postulates (parallel postulate, equality of right angles, equality of all right angles, congruence of triangles, and the whole is greater than the part) served as the foundation for geometric reasoning
Archimedes' contributions
(c. 287-212 BCE) made significant advances in geometry, mechanics, and hydrostatics
Developed formulas for the volume and surface area of a sphere and cylinder
Used the to approximate the value of pi (π) and calculate the area under a parabola
Apollonius and conic sections
Apollonius of Perga (c. 262-190 BCE) wrote a (circles, ellipses, parabolas, hyperbolas)
Defined as the intersections of a plane with a double cone
Developed a system of naming and classifying conic sections based on their properties
