print("5" + "3") Why was the output 53 ?

Answer 1

As 5 written in double inverted commas("5"): Its a String....and as so 3, they are not the numbers but they are Strings, If you add an String to another string the output would be: "5" + "3" = 53

and in an int, double, float or long case:
5 + 3 = 8;
Remember when we add double inverted commas to anything, it becomes a String😎

Answer 2

Putting " around something makes it a string. So it makes it a character with no numerical value. So "a" + "b" = ab

Answer 3

8
