OK, let's work through this together. We're starting with 580 and we're going to multiply it by 33, which means we add 580 to itself 33 times.
Step 1: 0 + 580 = 580
Step 2: 580 + 580 = 1160
Step 3: 1160 + 580 = 1740
Step 4: 1740 + 580 = 2320
Step 5: 2320 + 580 = 2900
Step 6: 2900 + 580 = 3480
Step 7: 3480 + 580 = 4060
Step 8: 4060 + 580 = 4640
Step 9: 4640 + 580 = 5220
Step 10: 5220 + 580 = 5800
Step 11: 5800 + 580 = 6380
Step 12: 6380 + 580 = 6960
Step 13: 6960 + 580 = 7540
Step 14: 7540 + 580 = 8120
Step 15: 8120 + 580 = 8700
Step 16: 8700 + 580 = 9280
Step 17: 9280 + 580 = 9860
Step 18: 9860 + 580 = 10440
Step 19: 10440 + 580 = 11020
Step 20: 11020 + 580 = 11600
Step 21: 11600 + 580 = 12180
Step 22: 12180 + 580 = 12760
Step 23: 12760 + 580 = 13340
Step 24: 13340 + 580 = 13920
Step 25: 13920 + 580 = 14500
Step 26: 14500 + 580 = 15080
Step 27: 15080 + 580 = 15660
Step 28: 15660 + 580 = 16240
Step 29: 16240 + 580 = 16820
Step 30: 16820 + 580 = 17400
Step 31: 17400 + 580 = 17980
Step 32: 17980 + 580 = 18560
Step 33: 18560 + 580 = 19140

So, 580*33 = 19140
