The Number System could be the list of pointers that gives meaning to expressions penned in that amount method. For example, if we want to Categorical that We've 10 pet dogs, while in the decimal quantity program we'd publish “10 puppies,” during the binary method “1010 pet dogs,” inside the octal technique “twelve pet dogs,” and from the hexadecimal program “A puppies.” All these statements characterize ten puppies but in various selection units.
