Without delay, let's solve this. We've got 735 and we will be multiplying it by 27, that is, adding 735 to itself 27 times.
Step 1: 0 + 735 = 735
Step 2: 735 + 735 = 1470
Step 3: 1470 + 735 = 2205
Step 4: 2205 + 735 = 2940
Step 5: 2940 + 735 = 3675
Step 6: 3675 + 735 = 4410
Step 7: 4410 + 735 = 5145
Step 8: 5145 + 735 = 5880
Step 9: 5880 + 735 = 6615
Step 10: 6615 + 735 = 7350
Step 11: 7350 + 735 = 8085
Step 12: 8085 + 735 = 8820
Step 13: 8820 + 735 = 9555
Step 14: 9555 + 735 = 10290
Step 15: 10290 + 735 = 11025
Step 16: 11025 + 735 = 11760
Step 17: 11760 + 735 = 12495
Step 18: 12495 + 735 = 13230
Step 19: 13230 + 735 = 13965
Step 20: 13965 + 735 = 14700
Step 21: 14700 + 735 = 15435
Step 22: 15435 + 735 = 16170
Step 23: 16170 + 735 = 16905
Step 24: 16905 + 735 = 17640
Step 25: 17640 + 735 = 18375
Step 26: 18375 + 735 = 19110
Step 27: 19110 + 735 = 19845

So, 735*27 = 19845
