Overview Of Number Bases - SS3 ICT Past Questions and Answers - page 3

The base of a number system affects calculations and arithmetic operations by determining the number of unique digits available and how those digits are weighted. In different bases, addition, subtraction, multiplication, and division are performed using the rules specific to that base. For example, in base-10 (decimal), we carry over when adding 9 + 1. In base-2 (binary), we carry over when adding 1 + 1, and so on. The choice of base can affect the ease of performing certain operations and can impact the efficiency of calculations in specific contexts.
