Alright, let's solve this math problem step by step. First, we have the number 853. 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 853 and add it to itself 9 times.
Step 1: 0 + 853 = 853
Step 2: 853 + 853 = 1706
Step 3: 1706 + 853 = 2559
Step 4: 2559 + 853 = 3412
Step 5: 3412 + 853 = 4265
Step 6: 4265 + 853 = 5118
Step 7: 5118 + 853 = 5971
Step 8: 5971 + 853 = 6824
Step 9: 6824 + 853 = 7677

So, 853*9 = 7677
