Because [*"the addition operator produces the sum of numeric operands or string concatenation."*](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Arithmetic_Operators#Addition). The other arithmetic operands are defined only for numbers and they convert their operands to numbers before using them. – axiac Jul 16 '18 at 09:24
