What happens first
Multiplication and division happen before addition and subtraction, and comparisons happen last. Use parentheses when you want something else.

bhana((1 + 2) * 3);
bhana(2 + 3 > 4);7

sahiFrom strongest to weakest:
- Calls:
jod(1, 2) - Prefix:
-x,!x */+-<>==!=
Comparisons all have the same strength, so a < b == sahi is read left to right as (a < b) == sahi.
The parser that decides this is a Pratt parser. How Lipi works explains it.
