OK, let's work through this together. We're starting with 582 and we're going to multiply it by 29, which means we add 582 to itself 29 times.
Step 1: 0 + 582 = 582
Step 2: 582 + 582 = 1164
Step 3: 1164 + 582 = 1746
Step 4: 1746 + 582 = 2328
Step 5: 2328 + 582 = 2910
Step 6: 2910 + 582 = 3492
Step 7: 3492 + 582 = 4074
Step 8: 4074 + 582 = 4656
Step 9: 4656 + 582 = 5238
Step 10: 5238 + 582 = 5820
Step 11: 5820 + 582 = 6402
Step 12: 6402 + 582 = 6984
Step 13: 6984 + 582 = 7566
Step 14: 7566 + 582 = 8148
Step 15: 8148 + 582 = 8730
Step 16: 8730 + 582 = 9312
Step 17: 9312 + 582 = 9894
Step 18: 9894 + 582 = 10476
Step 19: 10476 + 582 = 11058
Step 20: 11058 + 582 = 11640
Step 21: 11640 + 582 = 12222
Step 22: 12222 + 582 = 12804
Step 23: 12804 + 582 = 13386
Step 24: 13386 + 582 = 13968
Step 25: 13968 + 582 = 14550
Step 26: 14550 + 582 = 15132
Step 27: 15132 + 582 = 15714
Step 28: 15714 + 582 = 16296
Step 29: 16296 + 582 = 16878

So, 582*29 = 16878
