Alright, let's solve this math problem step by step. First, we have the number 812. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 22. So, we're going to take the number 812 and add it to itself 22 times.
Step 1: 0 + 812 = 812
Step 2: 812 + 812 = 1624
Step 3: 1624 + 812 = 2436
Step 4: 2436 + 812 = 3248
Step 5: 3248 + 812 = 4060
Step 6: 4060 + 812 = 4872
Step 7: 4872 + 812 = 5684
Step 8: 5684 + 812 = 6496
Step 9: 6496 + 812 = 7308
Step 10: 7308 + 812 = 8120
Step 11: 8120 + 812 = 8932
Step 12: 8932 + 812 = 9744
Step 13: 9744 + 812 = 10556
Step 14: 10556 + 812 = 11368
Step 15: 11368 + 812 = 12180
Step 16: 12180 + 812 = 12992
Step 17: 12992 + 812 = 13804
Step 18: 13804 + 812 = 14616
Step 19: 14616 + 812 = 15428
Step 20: 15428 + 812 = 16240
Step 21: 16240 + 812 = 17052
Step 22: 17052 + 812 = 17864

So, 812*22 = 17864
