#include <bits/stdc++.h>

using namespace std;

typedef long long ll;

int main(){
    ll n, m;
    cin >> m >> n;

    ll oddr = 2ll * m;
    ll ever = 2ll * m - 2ll;
    ll bound = (n % 2ll == 0ll ? ever : oddr) + oddr * n + n + 1ll;

    //cout << bound << "\n";

    ll odds = m-1ll;
    ll eves = m-2ll;

    ll segs = eves * (n/2ll) + odds * ((n + 1ll)/2ll) + n - 1ll;

    //cout << segs << "\n";

    cout << (1ll + bound + (segs-1ll)/2ll) << "\n";

}
