XXXVII compared to subtraction rule numbers
Unlike numbers that use the subtraction rule, 37 uses only addition, making it easier to read:
Arabic number | Roman numeral | Method |
---|---|---|
35 | XXXV | 30 + 5 = addition only |
36 | XXXVI | 30 + 6 = addition only |
37 | XXXVII | 30 + 7 = addition only |
38 | XXXVIII | 30 + 8 = addition only |
39 | XXXIX | 30 + (10 - 1) = addition and subtraction |
40 | XL | 50 - 10 = subtraction only |
XXXVII is one of the last purely additive numbers before the Roman system transitions to using subtraction rules for efficiency.
How to remember the Roman thirty-seven notation?
To easily remember that 37 is written as XXXVII:
- Break it down: 37 = 30 + 7
- XXX represents thirty (three tens)
- VII represents seven (five plus two)
- Remember: XXXVII uses only addition, no subtraction needed
- Think of it as "thirty plus seven" in Roman symbols
Practical tip:
37 is the last number in the thirties that requires three X symbols. After 37, we move to numbers like 39 (XXXIX) that use subtraction, making XXXVII a good example of pure Roman addition.
XXXVII compared to other numbers in the thirties
Comparing 37 (XXXVII) with other numbers in the 30s shows the pattern of Roman numeral construction:
Arabic number | Roman numeral | Construction |
---|---|---|
34 | XXXIV | 30 + (5 - 1) |
35 | XXXV | 30 + 5 |
36 | XXXVI | 30 + 6 |
37 | XXXVII | 30 + 7 |
38 | XXXVIII | 30 + 8 |
39 | XXXIX | 30 + (10 - 1) |
40 | XL | 50 - 10 |
XXXVII represents one of the most straightforward constructions in Roman numerals, using pure addition without any subtraction rules.
Calculations using number XXXVII
Here are examples of how the number 37 (XXXVII) functions in simple operations:
Operation (Arabic) | Operation (Roman) | Result (Roman) | Result (Arabic) |
---|---|---|---|
37 + 3 | XXXVII + III | XL | 40 |
37 + 13 | XXXVII + XIII | L | 50 |
37 - 7 | XXXVII - VII | XXX | 30 |
37 - 1 | XXXVII - I | XXXVI | 36 |
37 + 2 | XXXVII + II | XXXIX | 39 |
These calculations demonstrate how XXXVII can be used in Roman arithmetic, though the Roman system was designed more for recording than calculating.
