Alright, let's solve this math problem step by step. First, we have the number 849. Next, we see the multiplication sign, which means we need to multiply something. And what are we multiplying it by? We multiply it by 9. So, we're going to take the number 849 and add it to itself 9 times.
Step 1: 0 + 849 = 849
Step 2: 849 + 849 = 1698
Step 3: 1698 + 849 = 2547
Step 4: 2547 + 849 = 3396
Step 5: 3396 + 849 = 4245
Step 6: 4245 + 849 = 5094
Step 7: 5094 + 849 = 5943
Step 8: 5943 + 849 = 6792
Step 9: 6792 + 849 = 7641

So, 849*9 = 7641
