Let's get this math done. We have 444 and we're going to multiply it by 31. This is the same as taking 444 and adding it to itself 31 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
Step 22: 9324 + 444 = 9768
Step 23: 9768 + 444 = 10212
Step 24: 10212 + 444 = 10656
Step 25: 10656 + 444 = 11100
Step 26: 11100 + 444 = 11544
Step 27: 11544 + 444 = 11988
Step 28: 11988 + 444 = 12432
Step 29: 12432 + 444 = 12876
Step 30: 12876 + 444 = 13320
Step 31: 13320 + 444 = 13764

So, 444*31 = 13764
