Let's get this math done. We have 772 and we're going to multiply it by 13. This is the same as taking 772 and adding it to itself 13 times.
Step 1: 0 + 772 = 772
Step 2: 772 + 772 = 1544
Step 3: 1544 + 772 = 2316
Step 4: 2316 + 772 = 3088
Step 5: 3088 + 772 = 3860
Step 6: 3860 + 772 = 4632
Step 7: 4632 + 772 = 5404
Step 8: 5404 + 772 = 6176
Step 9: 6176 + 772 = 6948
Step 10: 6948 + 772 = 7720
Step 11: 7720 + 772 = 8492
Step 12: 8492 + 772 = 9264
Step 13: 9264 + 772 = 10036

So, 772*13 = 10036
