Addition in JS?
I'm fairly new to code, but I've been trying to make a prompt-based calculator. Everything works fine, but addition works weirdly. Like, say if we did 7 + 5 it would come out as 75. Help?

Post the link to your code.

If you want to use only one prompt then you can use the native eval function to evaluate the statement.
This is a working prompt calculator:
alert(eval(prompt("Please enter a calculation:")));
(Input would look like "7+7*8")
And if you want to show the user multiple prompt, you could convert the string of each prompt to a number:
var firstNumber = Number(prompt("Enter your first number:"));
var secondNumber = Number(prompt("Enter your second Number"));
alert(firstNumber +" + "+ secondNumber+" = "+ (firstNumber+secondNumber) );

Maybe you declared 7 and 5 as strings? Where are your codes?

just transorm it into numbers and you're done.
You can check this one...but it uses JQ :D
