-Here, the first operand is a string, the compiller treats the other two operands as string too. The `2` gets concatinated to `'1'`, so it's like `'1' + 2 = "12"` and `"12" + 2 = "122"`

 The binary `+` is the only operator that supports strings in such a way. Other arithmetic operators work only with numbers and always convert their operands to numbers.
