OK, let's crack this. We're given 411 and our task is to multiply it by 30. Essentially, we'll be adding 411 to itself 30 times.
Step 1: 0 + 411 = 411
Step 2: 411 + 411 = 822
Step 3: 822 + 411 = 1233
Step 4: 1233 + 411 = 1644
Step 5: 1644 + 411 = 2055
Step 6: 2055 + 411 = 2466
Step 7: 2466 + 411 = 2877
Step 8: 2877 + 411 = 3288
Step 9: 3288 + 411 = 3699
Step 10: 3699 + 411 = 4110
Step 11: 4110 + 411 = 4521
Step 12: 4521 + 411 = 4932
Step 13: 4932 + 411 = 5343
Step 14: 5343 + 411 = 5754
Step 15: 5754 + 411 = 6165
Step 16: 6165 + 411 = 6576
Step 17: 6576 + 411 = 6987
Step 18: 6987 + 411 = 7398
Step 19: 7398 + 411 = 7809
Step 20: 7809 + 411 = 8220
Step 21: 8220 + 411 = 8631
Step 22: 8631 + 411 = 9042
Step 23: 9042 + 411 = 9453
Step 24: 9453 + 411 = 9864
Step 25: 9864 + 411 = 10275
Step 26: 10275 + 411 = 10686
Step 27: 10686 + 411 = 11097
Step 28: 11097 + 411 = 11508
Step 29: 11508 + 411 = 11919
Step 30: 11919 + 411 = 12330

So, 411*30 = 12330
