Alright, let's solve this math problem step by step. First, we have the number 884. 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 884 and add it to itself 24 times.
Step 1: 0 + 884 = 884
Step 2: 884 + 884 = 1768
Step 3: 1768 + 884 = 2652
Step 4: 2652 + 884 = 3536
Step 5: 3536 + 884 = 4420
Step 6: 4420 + 884 = 5304
Step 7: 5304 + 884 = 6188
Step 8: 6188 + 884 = 7072
Step 9: 7072 + 884 = 7956
Step 10: 7956 + 884 = 8840
Step 11: 8840 + 884 = 9724
Step 12: 9724 + 884 = 10608
Step 13: 10608 + 884 = 11492
Step 14: 11492 + 884 = 12376
Step 15: 12376 + 884 = 13260
Step 16: 13260 + 884 = 14144
Step 17: 14144 + 884 = 15028
Step 18: 15028 + 884 = 15912
Step 19: 15912 + 884 = 16796
Step 20: 16796 + 884 = 17680
Step 21: 17680 + 884 = 18564
Step 22: 18564 + 884 = 19448
Step 23: 19448 + 884 = 20332
Step 24: 20332 + 884 = 21216

So, 884*24 = 21216
