OK, let's work through this together. We're starting with 199 and we're going to multiply it by 27, which means we add 199 to itself 27 times.
Step 1: 0 + 199 = 199
Step 2: 199 + 199 = 398
Step 3: 398 + 199 = 597
Step 4: 597 + 199 = 796
Step 5: 796 + 199 = 995
Step 6: 995 + 199 = 1194
Step 7: 1194 + 199 = 1393
Step 8: 1393 + 199 = 1592
Step 9: 1592 + 199 = 1791
Step 10: 1791 + 199 = 1990
Step 11: 1990 + 199 = 2189
Step 12: 2189 + 199 = 2388
Step 13: 2388 + 199 = 2587
Step 14: 2587 + 199 = 2786
Step 15: 2786 + 199 = 2985
Step 16: 2985 + 199 = 3184
Step 17: 3184 + 199 = 3383
Step 18: 3383 + 199 = 3582
Step 19: 3582 + 199 = 3781
Step 20: 3781 + 199 = 3980
Step 21: 3980 + 199 = 4179
Step 22: 4179 + 199 = 4378
Step 23: 4378 + 199 = 4577
Step 24: 4577 + 199 = 4776
Step 25: 4776 + 199 = 4975
Step 26: 4975 + 199 = 5174
Step 27: 5174 + 199 = 5373

So, 199*27 = 5373
