Sure thing, let's get straight to it. We start with 594 and we're going to multiply it by 30, which means adding 594 to itself 30 times.
Step 1: 0 + 594 = 594
Step 2: 594 + 594 = 1188
Step 3: 1188 + 594 = 1782
Step 4: 1782 + 594 = 2376
Step 5: 2376 + 594 = 2970
Step 6: 2970 + 594 = 3564
Step 7: 3564 + 594 = 4158
Step 8: 4158 + 594 = 4752
Step 9: 4752 + 594 = 5346
Step 10: 5346 + 594 = 5940
Step 11: 5940 + 594 = 6534
Step 12: 6534 + 594 = 7128
Step 13: 7128 + 594 = 7722
Step 14: 7722 + 594 = 8316
Step 15: 8316 + 594 = 8910
Step 16: 8910 + 594 = 9504
Step 17: 9504 + 594 = 10098
Step 18: 10098 + 594 = 10692
Step 19: 10692 + 594 = 11286
Step 20: 11286 + 594 = 11880
Step 21: 11880 + 594 = 12474
Step 22: 12474 + 594 = 13068
Step 23: 13068 + 594 = 13662
Step 24: 13662 + 594 = 14256
Step 25: 14256 + 594 = 14850
Step 26: 14850 + 594 = 15444
Step 27: 15444 + 594 = 16038
Step 28: 16038 + 594 = 16632
Step 29: 16632 + 594 = 17226
Step 30: 17226 + 594 = 17820

So, 594*30 = 17820
