Let's roll up our sleeves and solve this. We have 349 and we're going to multiply it by 27, essentially adding 349 to itself 27 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
Step 12: 3839 + 349 = 4188
Step 13: 4188 + 349 = 4537
Step 14: 4537 + 349 = 4886
Step 15: 4886 + 349 = 5235
Step 16: 5235 + 349 = 5584
Step 17: 5584 + 349 = 5933
Step 18: 5933 + 349 = 6282
Step 19: 6282 + 349 = 6631
Step 20: 6631 + 349 = 6980
Step 21: 6980 + 349 = 7329
Step 22: 7329 + 349 = 7678
Step 23: 7678 + 349 = 8027
Step 24: 8027 + 349 = 8376
Step 25: 8376 + 349 = 8725
Step 26: 8725 + 349 = 9074
Step 27: 9074 + 349 = 9423

So, 349*27 = 9423
