OK, let's work through this together. We're starting with 751 and we're going to multiply it by 30, which means we add 751 to itself 30 times.
Step 1: 0 + 751 = 751
Step 2: 751 + 751 = 1502
Step 3: 1502 + 751 = 2253
Step 4: 2253 + 751 = 3004
Step 5: 3004 + 751 = 3755
Step 6: 3755 + 751 = 4506
Step 7: 4506 + 751 = 5257
Step 8: 5257 + 751 = 6008
Step 9: 6008 + 751 = 6759
Step 10: 6759 + 751 = 7510
Step 11: 7510 + 751 = 8261
Step 12: 8261 + 751 = 9012
Step 13: 9012 + 751 = 9763
Step 14: 9763 + 751 = 10514
Step 15: 10514 + 751 = 11265
Step 16: 11265 + 751 = 12016
Step 17: 12016 + 751 = 12767
Step 18: 12767 + 751 = 13518
Step 19: 13518 + 751 = 14269
Step 20: 14269 + 751 = 15020
Step 21: 15020 + 751 = 15771
Step 22: 15771 + 751 = 16522
Step 23: 16522 + 751 = 17273
Step 24: 17273 + 751 = 18024
Step 25: 18024 + 751 = 18775
Step 26: 18775 + 751 = 19526
Step 27: 19526 + 751 = 20277
Step 28: 20277 + 751 = 21028
Step 29: 21028 + 751 = 21779
Step 30: 21779 + 751 = 22530

So, 751*30 = 22530
