Let's get this math done. We have 549 and we're going to multiply it by 19. This is the same as taking 549 and adding it to itself 19 times.
Step 1: 0 + 549 = 549
Step 2: 549 + 549 = 1098
Step 3: 1098 + 549 = 1647
Step 4: 1647 + 549 = 2196
Step 5: 2196 + 549 = 2745
Step 6: 2745 + 549 = 3294
Step 7: 3294 + 549 = 3843
Step 8: 3843 + 549 = 4392
Step 9: 4392 + 549 = 4941
Step 10: 4941 + 549 = 5490
Step 11: 5490 + 549 = 6039
Step 12: 6039 + 549 = 6588
Step 13: 6588 + 549 = 7137
Step 14: 7137 + 549 = 7686
Step 15: 7686 + 549 = 8235
Step 16: 8235 + 549 = 8784
Step 17: 8784 + 549 = 9333
Step 18: 9333 + 549 = 9882
Step 19: 9882 + 549 = 10431

So, 549*19 = 10431
