Greater than, less than
The question
20 ? 19
20 (2 digits)?19 (2 digits)
from the left:20vs19
20>19
20 (2 digits)vs19 (2 digits)
20>19
- Count the digits first — more digits means bigger. These two have the same number of digits.
- Compare the digits from the left, where they are worth the most.
- The first place they differ decides it: 20 is the bigger.
- So 20 > 19 — the open end of the sign always faces the bigger number.
