Alright, let's solve this math problem step by step. First, we have the number 814. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 30. So, we're going to take the number 814 and add it to itself 30 times.
Step 1: 0 + 814 = 814
Step 2: 814 + 814 = 1628
Step 3: 1628 + 814 = 2442
Step 4: 2442 + 814 = 3256
Step 5: 3256 + 814 = 4070
Step 6: 4070 + 814 = 4884
Step 7: 4884 + 814 = 5698
Step 8: 5698 + 814 = 6512
Step 9: 6512 + 814 = 7326
Step 10: 7326 + 814 = 8140
Step 11: 8140 + 814 = 8954
Step 12: 8954 + 814 = 9768
Step 13: 9768 + 814 = 10582
Step 14: 10582 + 814 = 11396
Step 15: 11396 + 814 = 12210
Step 16: 12210 + 814 = 13024
Step 17: 13024 + 814 = 13838
Step 18: 13838 + 814 = 14652
Step 19: 14652 + 814 = 15466
Step 20: 15466 + 814 = 16280
Step 21: 16280 + 814 = 17094
Step 22: 17094 + 814 = 17908
Step 23: 17908 + 814 = 18722
Step 24: 18722 + 814 = 19536
Step 25: 19536 + 814 = 20350
Step 26: 20350 + 814 = 21164
Step 27: 21164 + 814 = 21978
Step 28: 21978 + 814 = 22792
Step 29: 22792 + 814 = 23606
Step 30: 23606 + 814 = 24420

So, 814*30 = 24420
