Alright, let's solve this math problem step by step. First, we have the number 841. 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 841 and add it to itself 9 times.
Step 1: 0 + 841 = 841
Step 2: 841 + 841 = 1682
Step 3: 1682 + 841 = 2523
Step 4: 2523 + 841 = 3364
Step 5: 3364 + 841 = 4205
Step 6: 4205 + 841 = 5046
Step 7: 5046 + 841 = 5887
Step 8: 5887 + 841 = 6728
Step 9: 6728 + 841 = 7569

So, 841*9 = 7569
