Im confused if ('8' + 7) would be 87 or 15.

I'm confused every time I get a problem like that with a string number being added with an integer. Like would i add 8 and 7 or would i put those numbers together giving me 87

If you a add two strings, you'll be concatenating them e.g: "8"+"7" = "87" If you add two integers: 8 + 7 = 15 If you try to "add" a string and a integer you'll receive an error message PS: I'm considering Python 3

I have never seen languages where addition of string and number returns number as result. So just remember it and don't be confused next time 😉 In your case compiler automatically casts number (7) to string, so it works like '8' + '7' giving you string value '87'
