Without delay, let's solve this. We've got 853 and we will be multiplying it by 10, that is, adding 853 to itself 10 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
Step 10: 7677 + 853 = 8530

So, 853*10 = 8530
