CLI
151 is written CLI in Roman numerals. That is 3 symbol groups added together, reading left to right from the largest value down.
How it breaks down

| L | 50 | — | 150 |
| I | 1 | — | 151 |
No subtraction needed
CLI is purely additive — every symbol is simply added to the one before it, with no subtractive pairs like IV or IX. Numbers avoid subtraction when none of their digits is a 4 or a 9.
