2- There was the solution of equations, areas of geometric regions, volumes, etc.

1593 BCE

Middle Ages (17th Century)

John Napier
1- Created Logarithms because the operations of multiplication and division are reduced to simple addition and subtraction.
2- He invented wooden rods to make it easier to multiply and divide large numbers and find square and cube roots.

825 BCE

Algebra

Al-Khwarizmi, the Father of Geometry
Around 825 he wrote a book which is where he got the word algebra 2- Algebra means the 'restoration of broken parts'.
3- The book included word problems, especially dealing with inheritance.

820 BCE

Middle Ages (Islamic)

Muhammad Ibn
1- He gave an explanation for the algebraic solution of quadratic equations with positive roots and he was the first to teach algebra in an elementary form.

800 BCE

Ancient (India)

Baudhayan
1- Author of Sulbasutra, which contains geometric constructions for solving linear and quadratic equations.
2- It also talks about the Pythagorean Theorem for the diagonal of a square.

750 BCE

Ancient (India)

Manava
1- Contains approximate construction of circles from and squares from circles.

700 BCE

Calculus

1- Created by Babylions, Calculus is the mathematical study of continuous change.
2- It has two major branches: differential calculus and integral calculus.
3- These two branches are related to each other by the fundamental theorem of calculus.

624 BCE

Thales of Miletus (Greek)

Brought the science of Geometry from Egypt to Greece. He discovered 5 facts of elementary geometry, including an angle in a semi-circle in a right angle.

569 BCE

Pythagorus of Samos (Greek)

1- Created A squared plus B squared equals C squared.
2- For any right angled triangle the square of the length of the hypotenuse is equal to the sum of the right square of the other two sides.

500 BCE

Ancient (China)

1- Pascal's triangle is a number triangle with numbers in rows.
2- the triangle was studied by Blaise Pascal, but it was used centuries earlier by a Chinese mathematician.

500 BCE

Pythagorean Theorem

The Pythagorean Theorem was one of the earliest theorems known to ancient civilizations. It is named for the Greek mathematician and philosopher, Pythagoras.

470 BCE

Hippocrates of Chios (Greek)

1- Known for working on the cube, which he showed to be equivalent to constructing two mean proportions between a number and its double.

427 BCE

Plato (Greek)

1- Found "The Academy" in 387 BC, which flourished until 529 AD using mathematical objects as perfect forms.

417 BCE

Theaetetus of Athens (Greek)

1- Created solid Geomtry
2- First construct all 5 regular solids (Platonic)

400 BCE

Binomial Theorem

Created by Euclid, The Binomial Theorem is a quick way of expanding a binomial expression that has been raised to some power.

325 BCE

Euclid of Alexandria (Greek)

Father of Geometry

287 BCE

1- Greatest mathematician of antiquit
2- His methods anticipated the integral calculus
3- Father of Calculus

262 BCE

Apollonius of Perga (Greek)

1- He was called 'The Great Geometer'
2- famous work was "Conics"

190 BCE

Hipparchus of Rhodes (Greek)

1- He published several books of trigonometric tables and the methods for calculating them.
2-based on his tables he divided a circle into 360° with each degree divided into 60 minutes.

85 BCE

Claudius Ptolemy

1- Developed the geocentric theory of planetary motion.
2-

70 BCE

Menelaus of Alexandria (AD)

1- Created spherical geometry
2- for a quadrilateral inscribed in a circle, the product of its diagonals is equal to the sum of the products of its opposite sides.

11 BCE

Ancient (China)

China developed very large and negative numbers , decimals, place value system, binary system, algebra, geometry and trigonometry. Pascal's triangle is known to have existed in China centuries.
