Representing Clusters in Different Number Systems

  • The text discusses representing clusters of objects in different number systems.
  • Initially, the base ten system is explained, where the largest power of ten fitting into the cluster of 35 objects is 10.
  • Dividing the objects into groups of ten, it results in three groups of ten and five individual objects.
  • In base ten, this is represented as three tens and five ones, totaling 35.
  • Moving to base two, the largest power of two fitting into 35 is 32.
  • Dividing the objects accordingly, it results in one group of 32, one group of two, and one individual object.
  • In base two, this is represented as 100011, equating to 35.
  • The text then delves into base 16, the hexadecimal system, with 16 unique digits.
  • Dividing the 35 objects, it results in two groups of 16 and three individual objects.
  • In base 16, this is represented as 23, signifying two sixteens and three ones, totaling 35.
