Thanks for the question. I ran in to a similar situation while creating a query last week.

Nice question, and a nice example showing that data type issues don't always result in an error. Implicit conversion isn't always your friend.

I thought it will conevert everything to int. As the expression eveluates from right to left so from the right first plus will return 121 (120 will be converted to int) and so on and so forth.
but unfortunately my guess is wrong.


No, expressions evaluate from left to right.

I got it wrong because I'm so used to shortcutting the addition of 3 numbers in my head that I for some reason thought SQL Server could do the same. Too early in the morning, not enough coffee, {{insert additional generic excuse}}.

Nice question, learned something new today. I was quite sure the answer would be 251, but then I remembered data type precedence may be tricky.
