Tips
  • The number system was invented in India and came to
    Europe with the Arabs.
  • The great merit was the introduction of the concept and zero symbol
    which allowed a system where just ten symbols can represent any
    number no matter how big it might be and this simplifies the way of solving equations.
  • The system is dominated by decimals because it is made up
    of ten numbers which are: 0,1,2,3,4,5,6,7,8,9,
  • This number system is positional and each number represents
    a different value depending on where it is placed.
Curiosities
According to anthropoligical studies, the origin of the decimal system is in the ten fingers on our hands that were used for counting.
