Sure thing! We've got 349 and we're gonna multiply it by 11. That's the same as adding 349 to itself 11 times.
Step 1: 0 + 349 = 349
Step 2: 349 + 349 = 698
Step 3: 698 + 349 = 1047
Step 4: 1047 + 349 = 1396
Step 5: 1396 + 349 = 1745
Step 6: 1745 + 349 = 2094
Step 7: 2094 + 349 = 2443
Step 8: 2443 + 349 = 2792
Step 9: 2792 + 349 = 3141
Step 10: 3141 + 349 = 3490
Step 11: 3490 + 349 = 3839

So, 349*11 = 3839
