4. In the seventeenth century, Location Numerals were invented as a new way to represent numbers. Location Numerals have a lot in common with the binary number,system we use today, that tio Numerals, successive letters of the alphabet are used to represent the powers of two, starting with an the way to Z=225. To represent a given number as a Location Numeral (L.N), the number is expressed as the sum of powers of two with each power of two replaced by its corresponding letter A=2 B=21 E 2 and so on Let's consider the decimal number 19. 19can be expressed as a sum of powers oftwo like this: 16+2+1. So 19 would be written in binary like this: 10011. . we can covert 19 to L notation by choosing the letters that correspond with le EBA. Since changing the order of the letters does not change their value, INsull written in alphabetical order: ABE Here are a few more examples.
