OK, let's work through this together. We're starting with 727 and we're going to multiply it by 30, which means we add 727 to itself 30 times.
Step 1: 0 + 727 = 727
Step 2: 727 + 727 = 1454
Step 3: 1454 + 727 = 2181
Step 4: 2181 + 727 = 2908
Step 5: 2908 + 727 = 3635
Step 6: 3635 + 727 = 4362
Step 7: 4362 + 727 = 5089
Step 8: 5089 + 727 = 5816
Step 9: 5816 + 727 = 6543
Step 10: 6543 + 727 = 7270
Step 11: 7270 + 727 = 7997
Step 12: 7997 + 727 = 8724
Step 13: 8724 + 727 = 9451
Step 14: 9451 + 727 = 10178
Step 15: 10178 + 727 = 10905
Step 16: 10905 + 727 = 11632
Step 17: 11632 + 727 = 12359
Step 18: 12359 + 727 = 13086
Step 19: 13086 + 727 = 13813
Step 20: 13813 + 727 = 14540
Step 21: 14540 + 727 = 15267
Step 22: 15267 + 727 = 15994
Step 23: 15994 + 727 = 16721
Step 24: 16721 + 727 = 17448
Step 25: 17448 + 727 = 18175
Step 26: 18175 + 727 = 18902
Step 27: 18902 + 727 = 19629
Step 28: 19629 + 727 = 20356
Step 29: 20356 + 727 = 21083
Step 30: 21083 + 727 = 21810

So, 727*30 = 21810
