Calculator Digits

For most calculations we use only ten different digits (0 to 9). The number zero, becomes a placeholder for a new set of numbers. The next set consists of 10 times the amount, and then the next 10 times again. Just like when we tried to fold the paper, each set of numbers grows exponentially. By using zero as a place holder, we can write incredible large numbers in a very small amount of space.

Look at the following and see how each successive row contains more possible number combinations than the first.

  • 1 = ONE
  • 10 = TEN
  • 100 = ONE HUNDRED
  • 1,000 = ONE THOUSAND
  • 10,000 = TEN THOUSAND

One thousand thousand is one with six zeros. These are normally displayed as groups of triple digits, separated by a comma:


⚡ There used to be a disparity between the definition of a billion. The British billion was originally defined as 1,000,000,000,000 or 10¹² (one million million), however the short scale of 1,000,000,000 or 10⁹ (one thousand million) has been adopted globally for weights, measures and scientific calculations.

I sat on the beach with a 1$ calculator from Indonesia, that had 14 digits instead of 12, and so was able to work out the Code of the Universe.
