Abstract
Number system is the method of writing numerals to represent values. It is an integral part of computer science. It is therefore, necessary to provide computer scientists with a good understanding of number system concepts. Several methods exist in converting from one number system to another. In this paper, we introduce a new method, called the Inverted-Triangular-Technique for converting other number systems to Decimal. It adopts a graphical presentation that assumes the shape of an inverted triangle. Two models have been presented: one to handle Integer number conversions and the other handles the non-integer conversions. Demonstrations of the models are presented for clarity of understanding. This technique has been tested with numerous examples, and the benefits arising from its uses have been discussed.
