Sure thing! We've got 728 and we're gonna multiply it by 35. That's the same as adding 728 to itself 35 times.
Step 1: 0 + 728 = 728
Step 2: 728 + 728 = 1456
Step 3: 1456 + 728 = 2184
Step 4: 2184 + 728 = 2912
Step 5: 2912 + 728 = 3640
Step 6: 3640 + 728 = 4368
Step 7: 4368 + 728 = 5096
Step 8: 5096 + 728 = 5824
Step 9: 5824 + 728 = 6552
Step 10: 6552 + 728 = 7280
Step 11: 7280 + 728 = 8008
Step 12: 8008 + 728 = 8736
Step 13: 8736 + 728 = 9464
Step 14: 9464 + 728 = 10192
Step 15: 10192 + 728 = 10920
Step 16: 10920 + 728 = 11648
Step 17: 11648 + 728 = 12376
Step 18: 12376 + 728 = 13104
Step 19: 13104 + 728 = 13832
Step 20: 13832 + 728 = 14560
Step 21: 14560 + 728 = 15288
Step 22: 15288 + 728 = 16016
Step 23: 16016 + 728 = 16744
Step 24: 16744 + 728 = 17472
Step 25: 17472 + 728 = 18200
Step 26: 18200 + 728 = 18928
Step 27: 18928 + 728 = 19656
Step 28: 19656 + 728 = 20384
Step 29: 20384 + 728 = 21112
Step 30: 21112 + 728 = 21840
Step 31: 21840 + 728 = 22568
Step 32: 22568 + 728 = 23296
Step 33: 23296 + 728 = 24024
Step 34: 24024 + 728 = 24752
Step 35: 24752 + 728 = 25480

So, 728*35 = 25480
