Sure thing, let's get straight to it. We start with 523 and we're going to multiply it by 30, which means adding 523 to itself 30 times.
Step 1: 0 + 523 = 523
Step 2: 523 + 523 = 1046
Step 3: 1046 + 523 = 1569
Step 4: 1569 + 523 = 2092
Step 5: 2092 + 523 = 2615
Step 6: 2615 + 523 = 3138
Step 7: 3138 + 523 = 3661
Step 8: 3661 + 523 = 4184
Step 9: 4184 + 523 = 4707
Step 10: 4707 + 523 = 5230
Step 11: 5230 + 523 = 5753
Step 12: 5753 + 523 = 6276
Step 13: 6276 + 523 = 6799
Step 14: 6799 + 523 = 7322
Step 15: 7322 + 523 = 7845
Step 16: 7845 + 523 = 8368
Step 17: 8368 + 523 = 8891
Step 18: 8891 + 523 = 9414
Step 19: 9414 + 523 = 9937
Step 20: 9937 + 523 = 10460
Step 21: 10460 + 523 = 10983
Step 22: 10983 + 523 = 11506
Step 23: 11506 + 523 = 12029
Step 24: 12029 + 523 = 12552
Step 25: 12552 + 523 = 13075
Step 26: 13075 + 523 = 13598
Step 27: 13598 + 523 = 14121
Step 28: 14121 + 523 = 14644
Step 29: 14644 + 523 = 15167
Step 30: 15167 + 523 = 15690

So, 523*30 = 15690
