Let's roll up our sleeves and solve this. We have 574 and we're going to multiply it by 27, essentially adding 574 to itself 27 times.
Step 1: 0 + 574 = 574
Step 2: 574 + 574 = 1148
Step 3: 1148 + 574 = 1722
Step 4: 1722 + 574 = 2296
Step 5: 2296 + 574 = 2870
Step 6: 2870 + 574 = 3444
Step 7: 3444 + 574 = 4018
Step 8: 4018 + 574 = 4592
Step 9: 4592 + 574 = 5166
Step 10: 5166 + 574 = 5740
Step 11: 5740 + 574 = 6314
Step 12: 6314 + 574 = 6888
Step 13: 6888 + 574 = 7462
Step 14: 7462 + 574 = 8036
Step 15: 8036 + 574 = 8610
Step 16: 8610 + 574 = 9184
Step 17: 9184 + 574 = 9758
Step 18: 9758 + 574 = 10332
Step 19: 10332 + 574 = 10906
Step 20: 10906 + 574 = 11480
Step 21: 11480 + 574 = 12054
Step 22: 12054 + 574 = 12628
Step 23: 12628 + 574 = 13202
Step 24: 13202 + 574 = 13776
Step 25: 13776 + 574 = 14350
Step 26: 14350 + 574 = 14924
Step 27: 14924 + 574 = 15498

So, 574*27 = 15498
