Decimal System Comparison
The notation CXV demonstrates Roman numeral systematic additive construction with clear component organization.
- • Roman numerals: CXV = C + XV = 100 + 15 = 115
- • Decimal system: 115 = (1 × 100) + (1 × 10) + (5 × 1) = 115
- • Semiprime factorization: 115 = 5 × 23
Additive Progression Around 115
The number 115 shows systematic Roman numeral construction:
| Arabic | Roman | Explanation |
|---|---|---|
| 113 | CXIII | C + XIII = 100 + 13 = 113 |
| 114 | CXIV | C + XIV = 100 + 14 = 114 |
| 115 | CXV | C + XV = 100 + 15 = 115 |
| 116 | CXVI | C + XVI = 100 + 16 = 116 |
CXV demonstrates the return to pure additive notation after the mixed notation of CXIV.

Special Significance of 115
The number 115 is scientifically significant as the atomic number of Moscovium, a synthetic superheavy element first created in 2003. Mathematically, 115 is a semiprime (5 × 23) and a deficient number, with its proper divisors summing to only 29. Historically, 115 AD marked major revolts across the Roman Empire.
Mathematical Properties of 115
Mathematical characteristics that make 115 noteworthy:
- 115 is a semiprime (product of two primes: 5 × 23)
- It is a deficient number (sum of proper divisors: 29 < 115)
- Has 4 divisors: 1, 5, 23, 115
- In binary: 1110011, in hexadecimal: 73
- The sum of its digits is 7
- It is an emirpimes (reverse 511 = 7 × 73 is also semiprime)
Did You Know?
Element 115 (Moscovium) was named after the Moscow Oblast in Russia, honoring the region where it was first synthesized. Its discovery represents a major breakthrough in superheavy element research and confirms theoretical predictions about the island of stability.
Roman Numeral Pattern
The progression shows systematic 100s construction:
- CXIV (114) → CXV (115) → CXVI (116)
- Notice the return to pure additive notation after mixed CXIV
- The pattern shows Roman numeral logical construction principles
Frequently Asked Questions
Why is 115 written as CXV in Roman numerals?
CXV follows standard additive notation: C (100) + XV (15) = 115. This creates an efficient 3-symbol representation following proper descending value order.
What makes 115 scientifically significant?
Element 115 (Moscovium) is a synthetic superheavy element that provides crucial insights into nuclear physics and the theoretical island of stability. It was first synthesized in 2003 and officially named in 2016.
What happened in the year 115 AD?
The year 115 AD was marked by the Diaspora Revolt across Egypt, Libya, and Cyprus, while Emperor Trajan captured Ctesiphon in Mesopotamia. A revolt in Britain also led to the massacre of the Roman garrison at York.
What are the mathematical properties of 115?
115 is a semiprime (5 × 23) and a deficient number. It's also an emirpimes because its reverse (511 = 7 × 73) is also a semiprime, making it mathematically interesting.
How does element 115 relate to the island of stability?
Moscovium isotopes provide a pathway toward the theoretical island of stability, where superheavy nuclei may exhibit relatively longer half-lives due to favorable proton-to-neutron ratios.
How does CXV demonstrate Roman numeral efficiency?
CXV uses just 3 symbols to represent 115, following clear additive logic. The systematic construction C + XV shows how Roman numerals efficiently represent numbers using established patterns.
Summary
Notation Rules for 115
