Hindu-Arabic numerals

The number system we use to day is known as the Hindu-Arabic numbering system. This system made it possible to do algebra, something Roman numerals could not do which is why we no longer use Roman numerals today.

The properties for the Hindu-Arabic numbering system:

numerals 1 to 9 are 2,000 years old

• Indians developed decimal system, based on tens, each numeral is worth 10 times the numeral to its right

• Decimal system requires symbol for zero, to show empty places


Zero-The concept of nothing, but having a value

Zero is the most complex number in the Hindu-Arabic numbering system

Things we would not have with out zero

  • absolute value
  • binary code (computers)
  • numbers other than 1,2,3,4,5,6,7,8,9,-1,-2,-3,-4,-5,-6,-7,-8,-9
  • algebra
  • geometry


It is the oldest living religion. It has no actual founder. A big part of it evolves reincarnation and Karma. They both go with each other to determine what an individual is reborn as depending on how he treated others in his life.
