Without delay, let's solve this. We've got 722 and we will be multiplying it by 24, that is, adding 722 to itself 24 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

So, 722*24 = 17328
