Alright, let's solve this math problem step by step. First, we have the number 444. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 21. So, we're going to take the number 444 and add it to itself 21 times.
Step 1: 0 + 444 = 444
Step 2: 444 + 444 = 888
Step 3: 888 + 444 = 1332
Step 4: 1332 + 444 = 1776
Step 5: 1776 + 444 = 2220
Step 6: 2220 + 444 = 2664
Step 7: 2664 + 444 = 3108
Step 8: 3108 + 444 = 3552
Step 9: 3552 + 444 = 3996
Step 10: 3996 + 444 = 4440
Step 11: 4440 + 444 = 4884
Step 12: 4884 + 444 = 5328
Step 13: 5328 + 444 = 5772
Step 14: 5772 + 444 = 6216
Step 15: 6216 + 444 = 6660
Step 16: 6660 + 444 = 7104
Step 17: 7104 + 444 = 7548
Step 18: 7548 + 444 = 7992
Step 19: 7992 + 444 = 8436
Step 20: 8436 + 444 = 8880
Step 21: 8880 + 444 = 9324

So, 444*21 = 9324
