Without delay, let's solve this. We've got 188 and we will be multiplying it by 20, that is, adding 188 to itself 20 times.
Step 1: 0 + 188 = 188
Step 2: 188 + 188 = 376
Step 3: 376 + 188 = 564
Step 4: 564 + 188 = 752
Step 5: 752 + 188 = 940
Step 6: 940 + 188 = 1128
Step 7: 1128 + 188 = 1316
Step 8: 1316 + 188 = 1504
Step 9: 1504 + 188 = 1692
Step 10: 1692 + 188 = 1880
Step 11: 1880 + 188 = 2068
Step 12: 2068 + 188 = 2256
Step 13: 2256 + 188 = 2444
Step 14: 2444 + 188 = 2632
Step 15: 2632 + 188 = 2820
Step 16: 2820 + 188 = 3008
Step 17: 3008 + 188 = 3196
Step 18: 3196 + 188 = 3384
Step 19: 3384 + 188 = 3572
Step 20: 3572 + 188 = 3760

So, 188*20 = 3760
