How XXXIII is built

Roman numerals are written one place value at a time, largest first. 33 splits into 30 (tens) + 3 (ones), and each piece becomes its own group of symbols:

SymbolValueRunning totalNote
X1010
X1020
X1030
I131
I132
I133

Read left to right, the symbols add up: 10 + 10 + 10 + 1 + 1 + 1 = 33. XXXIII needs no subtractive pairs: every symbol in it is simply added, because no place value of 33 is a 4 or a 9.

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