ANCIENT NUMBER SYSTEM
  • At ancient their was no number system so they
    count ON THEIR FINGERS.This envolvedinto sign
    language for the hand to eye communication of
    numbers which ,while not writing ,gave way to
    written numbers

ANCIENT NUMBERS
  • THERE ARE SEVEN ANCIENT NUMBER SYSTEM IN THE
    WORLD-
  • NATURES ABACUS
  • EGYPTIAN NUMBERS
  • BABYLONIAN NUMBERS
  • ZERO AND ARABIC NUMBERS
  • THE ABACUS
  • ROMAN NUMERALS
  • BINARY NUMBERS

5
NATURES ABACUS
  • NATURES ABACUS IS A CALCULATING DEVICE MADE BY
    THE USEFULL THINGS OF THE NATURE
    LIKE-WOOD,seeds,ETC.THESE TYPE OF TOOLS WERE
    INVENTED MANY CENTURIES BEFORE.THESE TYPES OF
    ABACUS IS STILL USED BY THE MERCHANTS,TRADERS AND
    BY THE CLERKS ALSO .

  • The System Of Ancient Egyptian Numbers Was Used
    In Ancient Egypt In Around 3000 BC Until The
    Early First Millennium AD. It Was A System Of
    Numeration Based On The Scale Of Ten, Often
    Rounded Off To The Higher Power, Written In
    Hieroglyphs, But They Had No Concept Of A
    Place-valued System Such As The Decimal System
    Is.
  • The Hieratic Form Of Numerals Stressed An Exact
    Finite Series Notation, Ciphered One To One Onto
    The Egyptian Alphabet. The Ancient Egyptian
    System Used Bases Of Ten

  • BABYLONIA NUMBERS were written in cuneiform,
    using a wedge tipped reed stylus to make a mark
    on a soft clay tablet which would be exposed in
    the sun to harden to create a permanent record.
  • The Babylonians, who were famous for their
    astronomical observations and calculations (aided
    by their invention of the abacus), used a
    sexagesimal positional numeral system inherited
    from either the Sumerian or the Eblaite
    civilizations. Neither of the predecessors was a
    positional system (having a convention for which
    end of the numeral represented the units).

  • Arabic numerals or Hindu-Arabic numerals or
    Indo-Arabic numerals are the ten digits 0, 1, 2,
    3, 4, 5, 6, 7, 8, 9. They are the most common
    symbolic representation of numbers in the world
    today.
  • The first positional numerical system was
    developed in Babylon in the 2nd millennium BC.
    While it used a zero-like placeholder, the first
    true zero was developed by ancient mathematicians
    in the Indian Subcontinent. Arabic numerals are
    used to represent this Hindu-Arabic numeral
    system, in which a sequence of digits such as
    "975" is read as a single number.

  • The abacus (plural abaci or abacuses), also
    called a counting frame, is a calculating tool It
    is difficult to imagine counting without numbers,
    but there was a time when written numbers did not
    exist. The earliest counting device was the human
    hand and its fingers, the feet and toes. Then, as
    even larger quantities (larger than ten
    human-fingers and toes could represent) were
    counted, various natural items like pebbles and
    twigs were used to help keep count.
  • Merchants who traded goods not only needed a way
    to count goods they bought and sold, but also to
    calculate the cost of those goods. Until numbers
    were invented, counting devices were used to make
    everyday calculations. The abacus is one of many
    counting devices invented to help count large
    numbers.

  • Roman numerals, the numeric system used
    in ancient Rome, employs combinations of letters
    from the Latin alphabet to signify values. The
    numbers 1 to 10 can be expressed in Roman
    numerals as follows
  • I, II, III, IV, V, VI, VII, VIII, IX, X.
  • The Roman numeral system is a cousin of Etruscan
    numerals. Use of Roman numerals continued after
    the decline of the Roman Empire

11
  • In mathematics and digital electronics, a binary
    number is a number expressed in the binary
    numeral system, or base-2 numeral system, which
    represents numeric values using two different
    symbols typically 0 (zero) and 1 (one).
    The base-2 system is a positional notation with
    a radix of 2. Because of its straightforward
    implementation in digital electronic
    circuitry using logic gates, the binary system is
    used internally by almost all modern computers
    and computer-based devices. Each digit is
    referred to as a bit
