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.
