Alright, let's solve this math problem step by step. First, we have the number 651. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 24. So, we're going to take the number 651 and add it to itself 24 times.
Step 1: 0 + 651 = 651
Step 2: 651 + 651 = 1302
Step 3: 1302 + 651 = 1953
Step 4: 1953 + 651 = 2604
Step 5: 2604 + 651 = 3255
Step 6: 3255 + 651 = 3906
Step 7: 3906 + 651 = 4557
Step 8: 4557 + 651 = 5208
Step 9: 5208 + 651 = 5859
Step 10: 5859 + 651 = 6510
Step 11: 6510 + 651 = 7161
Step 12: 7161 + 651 = 7812
Step 13: 7812 + 651 = 8463
Step 14: 8463 + 651 = 9114
Step 15: 9114 + 651 = 9765
Step 16: 9765 + 651 = 10416
Step 17: 10416 + 651 = 11067
Step 18: 11067 + 651 = 11718
Step 19: 11718 + 651 = 12369
Step 20: 12369 + 651 = 13020
Step 21: 13020 + 651 = 13671
Step 22: 13671 + 651 = 14322
Step 23: 14322 + 651 = 14973
Step 24: 14973 + 651 = 15624

So, 651*24 = 15624
