- If you execute SELECT -100/-100*10 the result is 0.
- If you execute SELECT (-100/-100)*10 the result is 10.
- If you execute SELECT -100/(-100*10) the result is 0.

BOL states:

When two operators in an expression have the same operator precedence level, they are evaluated left to right based on their position in the expression.

And

Level Operators

1 ~ (Bitwise NOT)

2 * (Multiplication), / (Division), % (Modulus)

3 + (Positive), - (Negative), + (Addition), + (Concatenation), - (Subtraction), & (Bitwise AND), ^ (Bitwise Exclusive OR), | (Bitwise OR)

Is BOL wrong, or am I missing something? It seems the - is throwing the (expected) precedence off.
