const rl = require("readline").createInterface({ input: process.stdin });
var iter = rl[Symbol.asyncIterator]();
const readline = async () => (await iter.next()).value;

void async function () {
    let firstLine = await readline();
    let t = parseInt(firstLine);
    let res = 0;
    let token = await readline();
    let num = token.trim().split(' ').filter(item => item !== '');
    for (let i = 0; i < num.length; i++) {
        let n = parseInt(num[i])//注意, parseInt一次转单个字符串
        res += n;
    }
    console.log(res);
    }()
