OK, let's crack this. We're given 714 and our task is to multiply it by 23. Essentially, we'll be adding 714 to itself 23 times.
Step 1: 0 + 714 = 714
Step 2: 714 + 714 = 1428
Step 3: 1428 + 714 = 2142
Step 4: 2142 + 714 = 2856
Step 5: 2856 + 714 = 3570
Step 6: 3570 + 714 = 4284
Step 7: 4284 + 714 = 4998
Step 8: 4998 + 714 = 5712
Step 9: 5712 + 714 = 6426
Step 10: 6426 + 714 = 7140
Step 11: 7140 + 714 = 7854
Step 12: 7854 + 714 = 8568
Step 13: 8568 + 714 = 9282
Step 14: 9282 + 714 = 9996
Step 15: 9996 + 714 = 10710
Step 16: 10710 + 714 = 11424
Step 17: 11424 + 714 = 12138
Step 18: 12138 + 714 = 12852
Step 19: 12852 + 714 = 13566
Step 20: 13566 + 714 = 14280
Step 21: 14280 + 714 = 14994
Step 22: 14994 + 714 = 15708
Step 23: 15708 + 714 = 16422

So, 714*23 = 16422
