Alright, let's solve this math problem step by step. First, we have the number 429. 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 429 and add it to itself 24 times.
Step 1: 0 + 429 = 429
Step 2: 429 + 429 = 858
Step 3: 858 + 429 = 1287
Step 4: 1287 + 429 = 1716
Step 5: 1716 + 429 = 2145
Step 6: 2145 + 429 = 2574
Step 7: 2574 + 429 = 3003
Step 8: 3003 + 429 = 3432
Step 9: 3432 + 429 = 3861
Step 10: 3861 + 429 = 4290
Step 11: 4290 + 429 = 4719
Step 12: 4719 + 429 = 5148
Step 13: 5148 + 429 = 5577
Step 14: 5577 + 429 = 6006
Step 15: 6006 + 429 = 6435
Step 16: 6435 + 429 = 6864
Step 17: 6864 + 429 = 7293
Step 18: 7293 + 429 = 7722
Step 19: 7722 + 429 = 8151
Step 20: 8151 + 429 = 8580
Step 21: 8580 + 429 = 9009
Step 22: 9009 + 429 = 9438
Step 23: 9438 + 429 = 9867
Step 24: 9867 + 429 = 10296

So, 429*24 = 10296
