Without delay, let's solve this. We've got 693 and we will be multiplying it by 27, that is, adding 693 to itself 27 times.
Step 1: 0 + 693 = 693
Step 2: 693 + 693 = 1386
Step 3: 1386 + 693 = 2079
Step 4: 2079 + 693 = 2772
Step 5: 2772 + 693 = 3465
Step 6: 3465 + 693 = 4158
Step 7: 4158 + 693 = 4851
Step 8: 4851 + 693 = 5544
Step 9: 5544 + 693 = 6237
Step 10: 6237 + 693 = 6930
Step 11: 6930 + 693 = 7623
Step 12: 7623 + 693 = 8316
Step 13: 8316 + 693 = 9009
Step 14: 9009 + 693 = 9702
Step 15: 9702 + 693 = 10395
Step 16: 10395 + 693 = 11088
Step 17: 11088 + 693 = 11781
Step 18: 11781 + 693 = 12474
Step 19: 12474 + 693 = 13167
Step 20: 13167 + 693 = 13860
Step 21: 13860 + 693 = 14553
Step 22: 14553 + 693 = 15246
Step 23: 15246 + 693 = 15939
Step 24: 15939 + 693 = 16632
Step 25: 16632 + 693 = 17325
Step 26: 17325 + 693 = 18018
Step 27: 18018 + 693 = 18711

So, 693*27 = 18711
