Mathematics: Originates from Greek root words that tell us that the subject is about learning, not about numbers.
Babylonian mathematicians working in 2000 B.C.E., developed theories that were later tested and built upon by dedicated Greek thinkers.
Indian mathematicians working from 1500-1600 B.C.E. developed the concepts of zero and infinity as well as negative, irrational, and binary numbers.
The Arab countries were known to use three different types of counting systems in the eleventh century.
Mediums Used
- Babylonians used imperishable baked clay tablets
- Egyptians used stone and a kind of reed, papyrus.
- Early Chinese and lndians used very perishable media like bark and bamboo.
Mayan Numeral System has a symbol for '0'. This is written very simply by dots and dashes.
Roman Numeral System was decimal system, using letters. This way disabled them from calculating multi-digits number so they used abacus.
Hindu-Arabic Numeral System- Hindus invented it and Arabs spread it Europe
Famous Mathematicians
Isaac Newton – Calculus and Laws of motion
Brahmagupta – to treat zero as a number in its own right.
Gauss – Prince of Mathematics
Pythagoras –Father of Numbers
The abacus is a counting tool. The user of the abacus is called Abacist.
Kakuro Puzzle
Fill in the blank squares with numbers from 1 to 9, so that the numbers add up to the total required both horizontally and vertically. Each number can only be used once in each row or column. You will need to use both your adding and logic skills!

T
he Soma cube is not really a cube. It's a puzzle like Tangram. You have to rearrange puzzle pieces to form other figures. In fact there are 7 Soma-pieces like Tangram. But unlike Tangram the pieces from the Soma Cube are three-dimensional. The Soma-cube was conceived, according to Martin Gardner, by the Danish writer Piet Hein in 1936.
The Magic Square
A magic square is an arrangement of the numbers, with each number occurring exactly once, and such that the sum of the entries of any row, any column, or any main diagonal is the same.

In 1974, Rubik creates the first working prototype of the cube. This is the official birth date of the world’s favourite toy. In a classic Rubik's Cube, each of the six faces is covered by nine stickers, among six solid colours (traditionally white, red, blue, orange, green, and yellow)
