Why does " + " and " = " work shouldn't it be the string + and not actually + .

Why does " + " and " = " work shouldn't it be the string + and not actually + . I understand if we use + + it will give us error but why does this work.

It looks like you placed this question in the wrong category. It's about "JavaScript" (not "Java").

This exercise is a bit tricky, as it both does math and also displays math symbols. When you see the symbols inside quotes (like " + "), those symbols are part of the message that will be shown. The system treats them as strings and not as operators.

Then when you see the + symbol itself, it can be two things. When used with strings, it is the concatenation operator and joins the strings together. But when used with two numbers (like num1 + num2) it is the addition operator and adds the two numbers for a total. In this exercise you will see it used all 3 ways on the same line.

I hope that clears up the confusion!
