Without delay, let's solve this. We've got 93 and we will be multiplying it by 20, that is, adding 93 to itself 20 times.
Step 1: 0 + 93 = 93
Step 2: 93 + 93 = 186
Step 3: 186 + 93 = 279
Step 4: 279 + 93 = 372
Step 5: 372 + 93 = 465
Step 6: 465 + 93 = 558
Step 7: 558 + 93 = 651
Step 8: 651 + 93 = 744
Step 9: 744 + 93 = 837
Step 10: 837 + 93 = 930
Step 11: 930 + 93 = 1023
Step 12: 1023 + 93 = 1116
Step 13: 1116 + 93 = 1209
Step 14: 1209 + 93 = 1302
Step 15: 1302 + 93 = 1395
Step 16: 1395 + 93 = 1488
Step 17: 1488 + 93 = 1581
Step 18: 1581 + 93 = 1674
Step 19: 1674 + 93 = 1767
Step 20: 1767 + 93 = 1860

So, 93*20 = 1860
