#include <stdio.h>

int main()
{
    int n, k, i, o[11], s, powerout;
    
    scanf("%d", &n);
    while (n--)
    {
        s = 0;
        scanf("%d", &k);
        for(i = 0; i < k; i++)
        {
            scanf("%d", &o[i]);
            s += o[i];
        }
        powerout = s - (k-1);
        printf("%d\n", powerout);
    }
    
    return 0;
