#include<stdio.h>
int main() {
    int i,j,x;
    int a[3][2]= {{2,-6},{3,5},{1,-1}},b[2][4]= {{4,-2,-4,-5},{-7,-3,6,7}};
    int c[3][4]= {0};
    for(i=0; i<3; i++) {
        for(j=0; j<4; j++) {
            c[i][j] = 0;
            for(x=0; x<2; x++) {
                c[i][j] += a[i][x]*b[x][j];
            }
            printf("%d ",c[i][j]);
        }
        printf("\n");
    }
    return 0;
