POSTFIX NOTATION Postfix also known as Reverse Polish Notation (or RPN)‚ is a notational system where the operation/function follows the arguments. For example‚ "1 2 add" would be postfix notation for adding the numbers 1 and 2. Most programming languages use either prefix notation ("add(1‚ 2)" or "(add 1 2)") or infix notation ("1 add 2" or "1 + 2"). Prefix and infix are more familiar to most people‚ as they are the standard notations used for arithmetic and algebra. Why then should we use postfix

The binary numeral system‚ or base-2 number system‚ represents numeric values using two symbols‚ 0 and 1. More specifically‚ the usual base-2 system is a positional notation with a radix of 2. Because of its straightforward implementation in digital electronic circuitry using logic gates‚ the binary system is used internally by almost all modern computers. Why Computers Use Binary Binary numbers – seen as strings of 0’s and 1’s – are often associated with computers. But why is this? Why

of base 60 for no particular reason‚ but simply due to the fact that there is no suitable way to represent hours‚ minutes and seconds using the decimal numeral system.

Number Systems‚ Base Conversions‚ and Computer Data Representation Decimal and Binary Numbers When we write decimal (base 10) numbers‚ we use a positional notation system. Each digit is multiplied by an appropriate power of 10 depending on its position in the number: For example: 843 = 8 x 102 + 4 x 101 + 3 x 100 = 8 x 100 + 4 x 10 + 3 x 1 = 800 + 40 + 3 For whole numbers‚ the rightmost digit position is the one’s position (100 = 1). The numeral in that position indicates how many ones
