We now know that that there are situations where we need numbers, to express quantities in precise manner; for example, the following can only be expressed using numbers –

  1. Telephone numbers
  2. TV channels
  3. House numbers
  4. School admission numbers
  5. School bus seat numbers
  6. Timing of school periods
  7. Lunch period
  8. Prices of all the things you can buy in shops

Imagine what would happen if the above-mentioned things are expressed without using numbers.

Hint: the ’10-digit mobile phone numbers’ would become something like ‘acsdfghreq’ (i.e., using English alphabets) – far more difficult to recall or key in on a mobile phone. And why ‘acsdfghreq’ may be difficult compared to a mobile phone number ‘9813478654*’? It’s possible to easily read the number-based mobile number as a whole or in parts (e.g., it could be read as 98 and 134 and 786 and 54, or, 981, and 347, and 8654), meaningfully (i.e., 9, 8, 1, 8134, 786, 5, 54, 981, 347, 8654 are all ‘understandable’ numbers, unlike ‘acsd’, ‘fgh’, ‘req’ – these are not meaningful words).

*The example of a mobile phone is used here to leverage on the fact that every child is familiar with mobile numbers, without even knowing number representations, called numbers.
