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 26. So, we're going to take the number 853 and add it to itself 26 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
Step 11: 8530 + 853 = 9383
Step 12: 9383 + 853 = 10236
Step 13: 10236 + 853 = 11089
Step 14: 11089 + 853 = 11942
Step 15: 11942 + 853 = 12795
Step 16: 12795 + 853 = 13648
Step 17: 13648 + 853 = 14501
Step 18: 14501 + 853 = 15354
Step 19: 15354 + 853 = 16207
Step 20: 16207 + 853 = 17060
Step 21: 17060 + 853 = 17913
Step 22: 17913 + 853 = 18766
Step 23: 18766 + 853 = 19619
Step 24: 19619 + 853 = 20472
Step 25: 20472 + 853 = 21325
Step 26: 21325 + 853 = 22178

So, 853*26 = 22178
