Answer 1

Because after the first two numbers, there is a string and everything is evaluated as string and every number after the quotes is concatenated.

Answer 2

int: 1+1 = 2
String: 2+"1+1" = "21+1"
String: "21+1"+1 = "21+11"
String: "21+11"+1 = "21+111"

Answer 3

No, but the program didn't recognize the assignment as string until you wrote +"" then it started behaving like a string the same as if you will use the () as I hava already said the behavior will be like int because it doesn't care about the part outside

Answer 4

That is, despite the fact that this is String, the first two numbers are perceived as int?

Answer 5

Thanks everyone!

Answer 6

Because the "+" operator in the quoted string acts as a string delimiter operator :-) (two strings are concatenated)

Answer 7

In addition to TheWh¡teCat you can add () on the last two digits and see that they will evaluate to 2

Answer 8

2+1+2=21+2
