How XXXVIII is built

Roman numerals are written one place value at a time, largest first. 38 splits into 30 (tens) + 8 (ones), and each piece becomes its own group of symbols:

SymbolValueRunning totalNote
X1010
X1020
X1030
V535
I136
I137
I138

Read left to right, the symbols add up: 10 + 10 + 10 + 5 + 1 + 1 + 1 = 38. XXXVIII needs no subtractive pairs: every symbol in it is simply added, because no place value of 38 is a 4 or a 9.

The symbol X (10) is the largest one used to build XXXVIII -- it also shows up in 81 other numbers between 1 and 100.
