Alright, let's solve this math problem step by step. First, we have the number 847. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 23. So, we're going to take the number 847 and add it to itself 23 times.
Step 1: 0 + 847 = 847
Step 2: 847 + 847 = 1694
Step 3: 1694 + 847 = 2541
Step 4: 2541 + 847 = 3388
Step 5: 3388 + 847 = 4235
Step 6: 4235 + 847 = 5082
Step 7: 5082 + 847 = 5929
Step 8: 5929 + 847 = 6776
Step 9: 6776 + 847 = 7623
Step 10: 7623 + 847 = 8470
Step 11: 8470 + 847 = 9317
Step 12: 9317 + 847 = 10164
Step 13: 10164 + 847 = 11011
Step 14: 11011 + 847 = 11858
Step 15: 11858 + 847 = 12705
Step 16: 12705 + 847 = 13552
Step 17: 13552 + 847 = 14399
Step 18: 14399 + 847 = 15246
Step 19: 15246 + 847 = 16093
Step 20: 16093 + 847 = 16940
Step 21: 16940 + 847 = 17787
Step 22: 17787 + 847 = 18634
Step 23: 18634 + 847 = 19481

So, 847*23 = 19481
