For this challenge, let's pretend we're building a calculator that outputs a string with the result of a math operation.

For this challenge, let's pretend we're building a calculator that outputs a string with the result of a math operation.

Start by declaring two constants, firstValue and secondValue and to both of them assign some integer values (whatever you want! don't go too crazy though) Im Trying this code.

let firstVale: Int = 3 let secondValue: Int = 4 3+4 var Int = 3.0 firstVale + secondValue

types.swift 
let firstVale: Int = 3
let secondValue: Int = 2
firstVale + secondValue

Hey there Karthik,

the problem why you're not passing the task is that the first constant has to be called firstValue instead of firstVale. Also note that you don't have to use type annotation here and that you don't have to add both values together for the first task but if you want to that's fine as well! :)

The solution for the first task could look like this:

let firstValue = 3
let secondValue = 2

I hope that helps! :)
