# Trick to Adding String and Number
The unary + operator is a shortcut to convert a string into a number 🤩
Problem: Adding strings that contain numbers does NOT add them. Instead, the strings are concatenated ❌
Solution: Convert the string into a number. Then you can calculate the sum ✅
const string = '100';
const number = 5;
// This doesn't return the sum, it's concatentated
console.log(string + number); // 1005
// Prepend string with "+" to calculate the sum
console.log(+string + number); // 105
