Why do we use symbols to represent numbers?
Reason about patterns and symbols as arbitrary abstract concepts that can be used to represent numbers. Invent their own “number system” with symbols and rules for getting from one pattern to the next.
Can a computer understand the positional number system?
Computer – Number System. When we type some letters or words, the computer translates them in numbers as computers can understand only numbers. A computer can understand the positional number system where there are only a few symbols called digits and these symbols represent different values depending on the position they occupy in the number.
How are number systems and bases like odometers?
