@richard1234 - video solutions for these problems are currently not in the content roadmap.

include <stdio.h>
define ll long long int

int main(void) {
int t;
scanf(“%d”,&t);
while (t–)
{
ll n,m,new1;
scanf(“%lld%lld”,&n,&m);

    new1 = ((n*(n+1)) * (m*(m+1))/4)-(n*m);
    printf("%lld\n",new1);

}
return 0;

}
