Sure thing, let's get straight to it. We start with 722 and we're going to multiply it by 30, which means adding 722 to itself 30 times.
Step 1: 0 + 722 = 722
Step 2: 722 + 722 = 1444
Step 3: 1444 + 722 = 2166
Step 4: 2166 + 722 = 2888
Step 5: 2888 + 722 = 3610
Step 6: 3610 + 722 = 4332
Step 7: 4332 + 722 = 5054
Step 8: 5054 + 722 = 5776
Step 9: 5776 + 722 = 6498
Step 10: 6498 + 722 = 7220
Step 11: 7220 + 722 = 7942
Step 12: 7942 + 722 = 8664
Step 13: 8664 + 722 = 9386
Step 14: 9386 + 722 = 10108
Step 15: 10108 + 722 = 10830
Step 16: 10830 + 722 = 11552
Step 17: 11552 + 722 = 12274
Step 18: 12274 + 722 = 12996
Step 19: 12996 + 722 = 13718
Step 20: 13718 + 722 = 14440
Step 21: 14440 + 722 = 15162
Step 22: 15162 + 722 = 15884
Step 23: 15884 + 722 = 16606
Step 24: 16606 + 722 = 17328
Step 25: 17328 + 722 = 18050
Step 26: 18050 + 722 = 18772
Step 27: 18772 + 722 = 19494
Step 28: 19494 + 722 = 20216
Step 29: 20216 + 722 = 20938
Step 30: 20938 + 722 = 21660

So, 722*30 = 21660
