Sure thing! We've got 756 and we're gonna multiply it by 29. That's the same as adding 756 to itself 29 times.
Step 1: 0 + 756 = 756
Step 2: 756 + 756 = 1512
Step 3: 1512 + 756 = 2268
Step 4: 2268 + 756 = 3024
Step 5: 3024 + 756 = 3780
Step 6: 3780 + 756 = 4536
Step 7: 4536 + 756 = 5292
Step 8: 5292 + 756 = 6048
Step 9: 6048 + 756 = 6804
Step 10: 6804 + 756 = 7560
Step 11: 7560 + 756 = 8316
Step 12: 8316 + 756 = 9072
Step 13: 9072 + 756 = 9828
Step 14: 9828 + 756 = 10584
Step 15: 10584 + 756 = 11340
Step 16: 11340 + 756 = 12096
Step 17: 12096 + 756 = 12852
Step 18: 12852 + 756 = 13608
Step 19: 13608 + 756 = 14364
Step 20: 14364 + 756 = 15120
Step 21: 15120 + 756 = 15876
Step 22: 15876 + 756 = 16632
Step 23: 16632 + 756 = 17388
Step 24: 17388 + 756 = 18144
Step 25: 18144 + 756 = 18900
Step 26: 18900 + 756 = 19656
Step 27: 19656 + 756 = 20412
Step 28: 20412 + 756 = 21168
Step 29: 21168 + 756 = 21924

So, 756*29 = 21924
